Can a Slow, Precision Op Amp Drive a Fast 18-bit SAR ADC?

Kris Lokere - Strategic Applications Manager Mar 4th 2013
Many times the reference designs for high-speed high-resolution SAR ADCs show a relatively high-speed opamp in front of the ADC to drive it. There are good reasons for that: A low output impedance at high frequencies helps absorb the charge kick-back from the ADC’s sample capacitor, and the opamp’s high loop gain ...
