... AC specifications of the amplifier are not very critical. For high-speed applications slew-rate, openloop gain and gain/phase-margin specifications of the amplifier should be selected for the desired performance. The output impedance of the AD7541 looking into I varies between 10k (R FEEDBACK (R in parallel with the ladder resistance). FEED-BACK ...
