Design Principle Of Dual-channel Standard Digital Isolator

A dual-channel standard digital isolator is a circuit that isolates an input signal into two output signals. Its design principle is based on standard digital isolators, featuring high speed, high precision and wide acceptable input voltage range.

A standard digital isolator consists of three parts: an input, an isolation region, and an output. The input end is connected to a controller, ASIC or other systems to receive digital signals; the isolation area realizes the isolation of digital signals through magnetic coupling or photoelectric isolation; the output end transmits the isolated signal to other devices or controllers. The dual-channel standard digital isolator has two isolation areas, which can isolate two input signals and output two isolated digital signals at the same time, thereby realizing bidirectional isolation of signals.
