3 DescriptionThe TSV91x family, which includes single-, dual-, andquad-channel operational amplifiers (op amps), isspecifically designed for general-purposeapplications. Featuring rail-to-rail input and output(RRIO) swings, wide bandwidth (8 MHz), and lowoffset voltage (0.3 mV, typical), this family is designedfor a variety of applications that require a goodbalance between speed and power consumption. Theop amps are unity-gain stable and feature an ultra-low input bias current, which enables the family to beused in applications with high-source impedances.The low input bias current allows the devices to beused for sensor interfaces, battery-supplied andportable applications, and active filtering.

The robust design of the TSV91x provides ease-of-use to the circuit designer. Features include a unity-gain stable, integrated RFI-EMI rejection filter, nophase reversal in overdrive condition, and highelectrostatic discharge (ESD) protection (4-kV HBV).

8 Detailed Description

8.1 OverviewThe TSV91x series is a family of low-power, rail-to-rail input and output op amps. These devices operate from2.5 V to 5.5 V, are unity-gain stable, and are designed for a wide range of general-purpose applications. Theinput common-mode voltage range includes both rails and allows the TSV91x series to be used in virtually anysingle-supply application. Rail-to-rail input and output swing significantly increases dynamic range, especially inlow-supply applications and are designed for driving sampling analog-to-digital converters (ADCs).

8.2 Functional Block Diagram




http://www.ti.com





18




8.3 Feature Description

8.3.1 Rail-to-Rail InputThe input common-mode voltage range of the TSV91x family extends 100 mV beyond the supply rails for the fullsupply voltage range of 2.5 V to 5.5 V. This performance is achieved with a complementary input stage: an N-channel input differential pair in parallel with a P-channel differential pair, as shown in the Functional BlockDiagram. The N-channel pair is active for input voltages close to the positive rail, typically (V+) – 1.4 V to 100 mVabove the positive supply, whereas the P-channel pair is active for inputs from 100 mV below the negativesupply to approximately (V+) – 1.4 V. There is a small transition region, typically (V+) – 1.2 V to (V+) – 1 V, inwhich both pairs are on. This 200-mV transition region can vary up to 200 mV with process variation. Thus, thetransition region (with both stages on) can range from (V+) – 1.4 V to (V+) – 1.2 V on the low end, and up to(V+) – 1 V to (V+) – 0.8 V on the high end. Within this transition region, PSRR, CMRR, offset voltage, offset drift,and THD can degrade compared to device operation outside this region.

8.3.2 Rail-to-Rail OutputDesigned as a low-power, low-voltage operational amplifier, the TSV91x series delivers a robust output drivecapability. A class AB output stage with common-source transistors achieves full rail-to-rail output swingcapability. For resistive loads of 10 kΩ, the output swings to within 15 mV of either supply rail, regardless of theapplied power-supply voltage. Different load conditions change the ability of the amplifier to swing close to therails.

8.3.3 Overload RecoveryOverload recovery is defined as the time required for the operational amplifier output to recover from a saturatedstate to a linear state. The output devices of the operational amplifier enter a saturation region when the outputvoltage exceeds the rated operating voltage, because of the high input voltage or the high gain. After the deviceenters the saturation region, the charge carriers in the output devices require time to return to the linear state.After the charge carriers return to the linear state, the device begins to slew at the specified slew rate. Therefore,the propagation delay (in case of an overload condition) is the sum of the overload recovery time and the slewtime. The overload recovery time for the TSV91x series is approximately 200 ns.

8.4 Device Functional ModesThe TSV91x family has a single functional mode. These devices are powered on as long as the power-supplyvoltage is between 2.5 V (±1.25 V) and 5.5 V (±2.75 V).

9 Application and Implementation

NOTEInformation in the following applications sections is not part of the TI componentspecification, and TI does not warrant its accuracy or completeness. TI’s customers areresponsible for determining suitability of components for their purposes. Customers shouldvalidate and test their design implementation to confirm system functionality.

9.1 Application InformationThe TSV91x series features 8-MHz bandwidth and 4.5-V/µs slew rate with only 550-µA of supply current perchannel, providing good AC performance at low power consumption. DC applications are well served with a lowinput noise voltage of 18 nV / √Hz at 1 kHz, low input bias current, and a typical input offset voltage of 0.3 mV.

9.2 Typical ApplicationFigure 35 shows the TSV91x configured in a low-side, motor-control application.

Figure 35. TSV91x in a Low-Side, Motor-Control Application

9.2.1 Design RequirementsThe design requirements for this design are:

• Load current: 0 A to 1 A• Output voltage: 4.95 V• Maximum shunt voltage: 100 mV

Typical Application (continued)9.2.2 Detailed Design ProcedureThe transfer function of the circuit in Figure 35 is shown in Equation 1

(1)

The load current (ILOAD) produces a voltage drop across the shunt resistor (RSHUNT). The load current is set from0 A to 1 A. To keep the shunt voltage below 100 mV at maximum load current, the largest shunt resistor isdefined using Equation 2.

(2)

Using Equation 2, RSHUNT is 100 mΩ. The voltage drop produced by ILOAD and RSHUNT is amplified by the TSV91xto produce an output voltage of approximately 0 V to 4.95 V. The gain required by the TSV91x to produce thenecessary output voltage is calculated using Equation 3:

(3)

Using Equation 3, the required gain is calculated to be 49.5 V/V, which is set with resistors RF and RG.Equation 4 is used to size the resistors, RF and RG, to set the gain of the TSV91x to 49.5 V/V.

(4)

Selecting RF as 165 kΩ and RG as 3.4 kΩ provides a combination that equals roughly 49.5 V/V. Figure 36 showsthe measured transfer function of the circuit shown in Figure 35.

10 Power Supply RecommendationsThe TSV91x series is specified for operation from 2.5 V to 5.5 V (±1.25 V to ±2.75 V); many specifications applyfrom –40°C to +125°C. The Typical Characteristics section presents parameters that can exhibit significantvariance with regard to operating voltage or temperature.

CAUTIONSupply voltages larger than 6 V can permanently damage the device; see the AbsoluteMaximum Ratings table.

Place 0.1-µF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-impedance power supplies. For more detailed information on bypass capacitor placement, see the section.

10.1 Input and ESD ProtectionThe TSV91x series incorporates internal ESD protection circuits on all pins. For input and output pins, thisprotection consists of current-steering diodes connected between the input and power-supply pins. These ESDprotection diodes provide in-circuit, input overdrive protection, as long as the current is limited to 10-mA, asstated in the Absolute Maximum Ratings table. Figure 37 shows how a series input resistor is added to the driveninput to limit the input current. The added resistor contributes thermal noise at the amplifier input and the valuemust be kept to a minimum in noise-sensitive applications.

11 Layout

11.1 Layout GuidelinesFor best operational performance of the device, use good printed-circuit board (PCB) layout practices, including:

• Noise can propagate into analog circuitry through the power pins of the circuit as a whole and of op ampitself. Bypass capacitors are used to reduce the coupled noise by providing low-impedance powersources local to the analog circuitry.– Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as

close to the device as possible. A single bypass capacitor from V+ to ground is applicable for single-supply applications.

• Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effectivemethods of noise suppression. One or more layers on multilayer PCBs are usually devoted to groundplanes. A ground plane helps distribute heat and reduces electromagnetic interference (EMI) noisepickup. Make sure to physically separate digital and analog grounds, paying attention to the flow of theground current. For more detailed information, see Circuit Board Layout Techniques.

• To reduce parasitic coupling, run the input traces as far away from the supply or output traces aspossible. If these traces cannot be kept separate, crossing the sensitive trace perpendicular is muchbetter as opposed to in parallel with the noisy trace.

• Place the external components as close to the device as possible. As shown in Figure 39, keeping RFand RG close to the inverting input minimizes parasitic capacitance on the inverting input.

• Keep the length of input traces as short as possible. Always remember that the input traces are the mostsensitive part of the circuit.

• Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantlyreduce leakage currents from nearby traces that are at different potentials.

• Cleaning the PCB following board assembly is recommended for best performance.• Any precision integrated circuit can experience performance shifts resulting from moisture ingress into the

plastic package. Following any aqueous PCB cleaning process, baking the PCB assembly isrecommended to remove moisture introduced into the device packaging during the cleaning process. Alow-temperature, post-cleaning bake at 85°C for 30 minutes is sufficient for most circumstances.

TI is not responsible or liable for any such statements.Buyers and others who are developing systems that incorporate TI products (collectively, “Designers”) understand and agree that Designersremain responsible for using their independent analysis, evaluation and judgment in designing their applications and that Designers havefull and exclusive responsibility to assure the safety of Designers' applications and compliance of their applications (and of all TI productsused in or for Designers’ applications) with all applicable regulations, laws and other applicable requirements. Designer represents that, withrespect to their applications, Designer has all the necessary expertise to create and implement safeguards that (1) anticipate dangerousconsequences of failures, (2) monitor failures and their consequences, and (3) lessen the likelihood of failures that might cause harm andtake appropriate actions. Designer agrees that prior to using or distributing any applications that include TI products, Designer willthoroughly test such applications and the functionality of such TI products as used in such applications.TI’s provision of technical, application or other design advice, quality characterization, reliability data or other services or information,including, but not limited to, reference designs and materials relating to evaluation modules, (collectively, “TI Resources”) are intended toassist designers who are developing applications that incorporate TI products; by downloading, accessing or using TI Resources in anyway, Designer (individually or, if Designer is acting on behalf of a company, Designer’s company) agrees to use any particular TI Resourcesolely for this purpose and subject to the terms of this Notice.TI’s provision of TI Resources does not expand or otherwise alter TI’s applicable published warranties or warranty disclaimers for TIproducts, and no additional obligations or liabilities arise from TI providing such TI Resources. TI reserves the right to make corrections,enhancements, improvements and other changes to its TI Resources. TI has not conducted any testing other than that specificallydescribed in the published documentation for a particular TI Resource.Designer is authorized to use, copy and modify any individual TI Resource only in connection with the development of applications thatinclude the TI product(s) identified in such TI Resource.

Using products in an application does not by itself establish any safety features in the application. Designers mustensure compliance with safety-related requirements and standards applicable to their applications. Designer may not use any TI products inlife-critical medical equipment unless authorized officers of the parties have executed a special contract specifically governing such use.Life-critical medical equipment is medical equipment where failure of such equipment would cause serious bodily injury or death (e.g., lifesupport, pacemakers, defibrillators, heart pumps, neurostimulators, and implantables). Such equipment includes, without limitation, allmedical devices identified by the U.S. Food and Drug Administration as Class III devices and equivalent classifications outside the U.S.TI may expressly designate certain products as completing a particular qualification (e.g., Q100, Military Grade, or Enhanced Product).Designers agree that it has the necessary expertise to select the product with the appropriate qualification designation for their applicationsand that proper product selection is at Designers’ own risk.
