7.2 Typical Application

The following image shows the AMC1200C in a typical application. The load current flowing through an external shunt resistor RSHUNT produces a voltage drop. The AMC1200C high-side circuitry senses the voltage drop across the shunt resistor, then digitizes and transfers data across the isolation barrier to the low side. Low-side circuitry reconstructs the digitized data into an analog signal and provides the signal as a differential voltage on the output pins.

The differential input, differential output, and high common-mode transient immunity (CMTI) of the AMC1200C provide reliable and accurate operation even in high-noise environments.
