Working Principles

The AMC1203DW is an isolation amplifier that utilizes a sigma-delta modulator to convert the analog input signal into a digital representation. This digital data is then transmitted across the isolation barrier using a differential data transmission scheme. On the receiving side, the digital data is converted back into an analog signal using a digital-to-analog converter (DAC). The galvanic isolation between the input and output sides ensures accurate signal transmission while providing protection against voltage spikes and noise.
