ACPL-7900-000E [Broadcom]

ACPL-7900-000E  Description

The ACPL-790B/790A/7900 precision miniature isolation amplifiers were designed for current sensing and voltage sensing in electronic power converters applications such as 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.
