Interface High-Performance Op Amps With ADCs
The source that drives high-resolution analog-to-digital converters (ADCs) sees a high-frequency ac load and a dc load of a few hundred ohms or more. Thus, a high-performance op amp with high input impedance of a few megohms and low output impedance would be an ideal choice as an input ADC driver. The ADC driver acts as a buffer and a low-pass filter to reduce overall system noise. As signals travel through the traces of a printed-circuit board (PCB) and long cables, system noise...
