ADS1278 input

Other Parts Discussed in Thread: ADS1278, OPA1632

Hi,

I'm starting to design a multichannel acquisition system based on the ADS1278.in my project ,there is 40V peak-to-peak(+/- 20) differential signal that should digitize by ads1278. This ADC has +/- 2.5V input range. What is the best way to convert 40V peak-to-peak to 5V peak-to-peak with best performance?Can i combine this PGA with adc driver and input active low pass filter(opa1632)?

Regards
