Overview

This TI Verified Design implements a variety of op amps driving capacitive loads from 100pF to 1uF using a isolation resistor. The OPA192 is highlighted due to its ability to drive large capacitive loads with small isolation resistors.

Features

Supply Voltage: 30 V (+/-15 V)
Capacitive Loads: 100 pF, 1000 pF, 0.01 mF, 0.1 mF, 1 mF
Features the OPA192 High Voltage, Rail-to-Rail Input/Output,Precision Op Amps, E-Trim™ Series Amplifier
