ACPL-C79A-500E Broadcom, Isolation Amplifier

The Broadcom ACPL-C79A isolation amplifiers were designed for current sensing and voltage sensing in electronic power converters in 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.
