Working Principles

The AMC1311BDWVR utilizes a delta-sigma modulation technique to convert the input current into a digital representation. The modulator consists of an analog front-end, a digital filter, and a serial interface. The input current is sampled and converted into a stream of digital bits, which are then processed to obtain the final output value.

The isolation barrier is achieved through integrated transformers that provide galvanic isolation between the input and output sides. This ensures that any potential difference or noise on the input side does not affect the measurement circuitry.
