Precision Isolation Amplifiers
Data Sheet
Description
The ACPL-790B/790A/7900 isolation amplifiers were designed for current 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. For general applications, the ACPL-790A (±1% gain tolerance) and the ACPL-7900 (±3% gain tolerance) are remended. For high...
