Hello,
I'm looking for an ADC that will pair with my Altera dev board through the HSMC port. I'm considering the ADS6445EVM or any other EVM as long as the ADC has a 14 bit resolution, 500k sps (all of the EVM ADCs are well over this rate), and more than 2 channels. My main concern is the input to the ADS6445EVM. I know the ADS6445EVM has a wideband differential op-amp (THS4509) that would allow a wider range of signals to be used with the ADC. What I want to input is a (+/-)3V analog differential signal (a <100 Hz sine wave). After looking through the documentation for the THS4509, I'm still unsure if this would be suitable.
I'd appreciate some ideas/feedback on if using the THS4509 chip is suitable for the signal I need to convert or alternate routes besides the EVM ADCs.
Thanks!
