ACNT-H79B Datasheet | Broadcom

Description The ACNT-H79B/H79A/H790 isolation amplifiers are designed 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. For general applications, the ACNT-H79A (±1% gain tolerance) and the ACNT-H790 (±3% gain tolerance) are remended. For high-precision applications, the ACNT-H79B (±0.5% gain tolerance) can be used. The ACNT-H79B/H79A/H790 offers wide creepage and clearance with a high mon-mode transient immunity of 15k V/μs. These features allows the ACNT-H79B/H79A/H790 to provide the precision and stability...
