A is a digital-to-analog converter with digital isolation and voltage/current conversion functions. It can isolate and transform the input signal, and output the transformed signal to different circuits, thereby achieving electrical isolation and signal conversion. This article will introduce the principles, characteristics and application areas of standard digital isolators.

1. Principle of standard digital isolators
The standard digital isolator converts the input signal from analog to digital and isolates the electrical connection between the input and output ends. The device consists of an analog part and a digital part. The analog part electrically isolates the input signal and converts it from analog to digital, then transmits the digital signal to the digital part for digital signal processing and transmission, and completes the digital-to-analog conversion at the output end. The digital part of the standard digital isolator is often implemented using a digital signal processor (DSP) or a microcontroller (MCU).
