Precision Full-Wave Rectifier – Dual-Supply

https://www.electronics-lab.com/precision-full-wave-rectifier-dual-supply/

This is a dual-supply precision full-wave rectifier board that can turn alternating current (AC) signals into single polarity signals. The OPAMPs, U1A, and U1B, buffer the input signal and compensate for the voltage drops across D1 and D2 allowing for small signal inputs. This implementation functions with limited distortion for 20Vpp input signals at frequencies […]
