Buffer Op Amp to Analog-to-Digital Converter Design: AC Coupled Differential Input, Dual Supply, Differential Op Amps, Differential Input to ADC

Problem:
How do I buffer the input of an Analog to Digital Converter (ADC) when I have an AC coupled differential input, dual power supply, differential op amps, and differential input to ADC?

Solution:
You have previously selected:






Fully differential applications are assumed to use the fully differential input of the ADC:
