World’s Largest Selection of I2C-Compatible ADCsChoose from 20 ADCs

Since introducing the MAX127/MAX128 in 1998, Maxim has continued to expand its I2C‡ ADC productportfolio. They were the industry’s first 12-bit I2C ADCs and provided 8 channels with a software-programmable inputrange. We now offer 8-, 10-, and 12-bit ADCs with 4 and 12 channels, and 14- and 16-bit single-channel I2C ADCs.With 20 I2C-compatible ADCs, Maxim has a larger selection than the rest of the competition combined.

16-Bit RISC Microcontroller128kB Flash, 12-Bit ADC, 12-Bit DACs, and CAN 2.0B Interface

Powerful, Highly Accurate ADC, DACs, and Low-Noise µC on the Same Chip!The MAXQ7654* is a smart data-acquisition system. This single chip is comprised of a 16-bit, low-power MAXQ20*

RISC microcontroller, a 16-channel, 12-bit, 500ksps SAR ADC, and a CAN bus interface.The MAXQ7654’s ADC can convert at rates up to 500ksps. The device measures up to 16 external, single-ended signals

or up to 8 differential signals. It can also be used to measure the AVDD analog supply voltage without external connections.Other analog functions include: dual 12-bit, buffered voltage-output, force/sense DACs; an uncommitted, low-power op amp; abandgap-based voltage reference with independent DAC and ADC buffers; local (die) temperature measurement; and remotetemperature sensing with a low-cost transistor.

Low-Power, Quiet µC Operates Seamlessly with Analog SignalsThe 16-bit MAXQ20 RISC microcontroller has 32kB, 64kB, or 128kB of flash memory that can be converted to mask-

programmable ROM. A CAN 2.0B interface and 4-wire SPI interface allow access to external automotive peripherals. A crystalceramic resonator, internal FLL, or external clock up to 8MHz can be used as a high-frequency clock source by the microcon-troller, ADC, and timers. The device has 22 general-purpose digital I/Os, most of which are multiplexed with other functions.

The Innovative MAXQ™ RISC ArchitectureMAXQ is an innovative RISC architecture, a new microcontroller core that combines high performance and

low power with a variety of complex analog functions. The difficulty facing the mixed-signal designer is achieving high microcontroller performance, while minimizing

clock noise that can affect sensitive analog circuits. The MAXQ architecture reduces noise through intelligent clockmanagement and utilization. This means that the MAXQ core enables clocks only to those circuits that requireclocking at any instant, thus reducing power consumption and providing a quiet environment optimal for analog inte-gration. Additionally, the MAXQ architecture performs many functions on each clock to maximize its performance.
