Part Number: AFE7222
The datasheet for the AFE722x family specifies the ADC's input DC resistance at >1MOhm in parallel with 4 pF. What is the differential input impedance (e.g. 50, 100 Ohms). The datasheet doesn't specify if the inputs are buffered either, so is there resistance/reactance versus frequency data available to design the appropriate impedance matching interface between an amplifier output and the ADC inputs?
