BROADCOM (AVAGO)ACNT-H79B-000EOptocoupler
The Broadcom ACNT-H79B 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. ±05% gain accuracy (ACNT-H79B) –50 ppm/°C low gain drift 06-mV input offset voltage 005% excellent linearity 60-dB SNR 200-kHz wide bandwidth (Typ) –40°C to +105°C operating temperature range Advanced sigma-delta (-) A/D modulation technology 15-mm stretched SO-8 package 05-mm distance through insulation (DTI) 15-kV/μs common-mode transient immunity
