CIRCUIT060008

Full-wave rectifier circuit

CIRCUIT060008

Overview

This absolute value circuit can turn alternating current (AC) signals to single polarity signals. This circuit functions with limited distortion for ±10-V input signals at frequencies up to 50kHz and for signals as small as ±25mV at frequencies up to 1kHz.
Features
  • 30V Split supply with ground reference 
  • Input: +/-25mV to +/-10V 
  • Output: 25mV to 10V
General-purpose op amps
TLV172 — Single, 36-V, 10-MHz, low-power operational amplifier for cost-sensitive applications
Precision op amps (Vos<1mV)
OPA197 — Single, 36-V, precision, rail-to-rail input output, low offset voltage op amp
