Half-wave rectifier circuit
CIRCUIT060009
Overview
The precision half-wave rectifier inverts and transfers only the negative-half input of a time varying input signal (preferably sinusoidal) to its output. By appropriately selecting the feedback resistor values, different gains can be achieved. Precision half-wave rectifiers are commonly used with other op amp circuits such as a peak-detector or bandwidth limited non-inverting amplifier to produce a DC output voltage. This configuration has been designed to work for sinusoidal input signals between 0.2mVpp and 4Vpp at frequencies up to 50kHz.
Features
- 5V Split supply
- Input: +/-0.2mVpp to +/-4Vpp
- Output: 0.1V to 2V
