Description

This TI Verified Design implements a single-supply full-wave rectifier. The design has been optimized to support excellent linearity for small-input voltage signals from 5mV – 200mV.  The design is used to turn low-level alternating current (ac) signals to positive polarity signals. The circuit is designed to function up to 50 kHz and has excellent linearity at signal levels as low as 5 mVpp. The circuit can be used in sensor acquisition or signal strength indication applications that need to quantify values of low-level input signals which have positive and negative polarities.

Features
  • TI Precision Designs: Verified Design includes Theory, Component Selection, TINA-TI
  • Simulation, PCB Schematic & Layout, Bill of Materials, and Measured Performance
  • Outputs the full-wave rectified (absolute value) of the input signal
  • Supports low-level input signals down to 5mV with excellent linearity
  • Operates from a +5V Supply
