Sebuah ADC tipe SAC 8 bit mempunyai resolusi 20 mV.
a. Hitunglah output digitalnya jika diberi input analog 2,17 V. [108 desimal = 0110 1100]
b. Hitunglah waktu conversi (tc) jika f clock= 1Mhz. [untuk SAC, tC = N x 1cycle clock. Jadi tC = 8 micro secon]
c. Berapa kali lebih cepat waktu konversi ADC tipe SAC ini Jika menggunakan ADC Digital Ramp
