A zero crossing detector is an electronic circuit used to detect the exact moment when the voltage of an alternating current (AC) signal passes through zero volts. In other words, the zero-crossing detection circuit detects when an AC signal voltage […]

This post shows the design of a low cost precision analog isolation amplifier using HCNR201 (HCNR200) optocoupler where input signal is galvanically isolated from output signal. The HCNR201/HCNR200 can be used to isolate analog signals in a wide variety of
