Hi ,
In our application ,the input to ADC is 0V to 2V pulses , instead of -1V to 1V. The ADC part which supports 2Vp-p can be used?. By using VCM pin of ADC, is it possible or we have to choose ADC which support input 4Vp-p. Pl suggest.

Dear Tom,
Thank you for reply. We have used ADS6142 in our old design,this part was used for -1V to 1V input signal range. Now requirement is input signal range 0 to 2V . Now we can go to any other new part. My doubt is any ADC which supports 2Vp-p input range can be used for 0 to 2V input range application.

Dear Yusuf,
Thank you for reply. Yes what you said is correct. Can you pl suggest input circuit of the ADC for getting input signal range 0 to 2V .

Hi yousuf,
Thank you for reply. Is it not possible with transformer ?

Hey Keshava,
The data sheet says 2Vpp is the recommended operating range but its actually the max Vpp. Therefore, have an amplifier in input stage to condition the signals amplitude before it reaches the ADC would be ideal.
