Hello All,

I am looking for an ADC with the below features:

Bipolar input (+/-10V range)

12-bit resolution

100 KHz sampling rate

10 microsec throughput speed

and most importantly it should operate on a single 3.3V


  In the existing design, the ADC used is ADS7808 which operates on single 5V supply. But in my new design, I want to use the 3.3V technology only. I also have +/-15V supplies on the board.


I am not able to find the ADC's which can operate on 3.3V and support bipolar input range of +/-10V with any manufacturers. Is it possible to design in such away?


Please help me in finding the suitable ADC for my new design.


Many Thanks in advance,
