BROADCOM ACPL-C72A-000E Optocoupler, 1 Channel, SSO, 8 Pins, 5 kVrms, 250 kHz

ACPL-C72A-000E is a precision miniature isolation amplifier. It is designed for current 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 shunt resistor and the resulting analogue voltage drop is sensed by the isolation amplifier. The product operates from a single 5V supply and provides excellent linearity and dynamic performance of 65dB SNR. It is approved by IEC/EN/DIN EN 60747-5-5: 1414Vpeak working insulation voltage, UL 1577: 5000Vrms/1min double protection rating, CSA: Component Acceptance Notice #5. It is used in applications such as current sensing in AC and servo motor drives, solar inverters, wind turbine inverters, industrial process control, data acquisition systems, switching power supply signal isolation, general-purpose analogue signal isolation, traditional current transducer replacements.
