Precision Sample and Hold Amplifier

View Full Size Image View Original Datasheet Precision Sample and Hold Amplifier

CMOS amplifiers are very good for use in Sample-and-Hold circuits because the pA's of bias current does not drain off charge held on the hold capacitor. A dual amplifier can be used to buffer the input signal and also the hold capacitor. The slew rate of the circuit is limited by the output current limit of the input amplifier charging the 0.1uF hold capacitor.
