TIPD128

Design files

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
