The Broadcom ACNT-H790 isolation amplifier designs for current and voltage sensing in electronic power converters for applications including motor drives and renewable energy systems. In a typical motor drive implementation, current flows through an external resistor and the resulting analog voltage drop is sensed by the isolation amplifier. A differential output voltage that is proportional to the current is created on the other side of the optical isolation barrier
