Bogey, First, I'm sorry I didn't get back to you earlier. I'm not sure that the ADS131E04 work in the application because of the input range. I had mentioned the ADS131A04 earlier and that may work better because of the input range. However, I still think it's important to get more information. Is the low supply operation from the AD9629 important? Do the ADCs need to be simultaneously sampled, or can they be multiplexed? I would note that the ADS131E04 has a PGA that limits the input range, so that single ended measurements may not be possible. What did you mean by the "thru bypass cap for 27kHz frequency"? What resolution is needed? I need as much information about the application as possible. The AD9629 is a very different part, and it may make more sense to use a SAR type ADC for this. Joseph Wu
