Slew rate limiter circuit

CIRCUIT060059

Overview

This circuit controls the slew rate of an analog gain stage. This circuit is intended for symmetrical slew rate applications. The desired slew rate must be slower than that of the op amp chosen to implement the slew rate limiter.
Features
  • Input: Vi = -10 V to 10 V
  • Output: Vo = -10 V to 10 V
  • Supply:
    • Vcc = 15 V
    • Vee = -15 V
    • Vref = 0 V
Precision op amps (Vos<1mV)
OPA192 — High-Voltage, Rail-to-Rail Input/Output, 5µV, 0.2µV/˚C, Precision Operational Amplifier
General-purpose op amps
TLV2372 — Dual, 16-V, 3-MHz, RRIO operational amplifier
