ACPL-C870-000E – AVAGO

The ACPL-C870-000E is a galvanically isolated operational amplifier manufactured by Avago Technologies, housed in a standard 8-pin small outline (SO-8) package. It incorporates Avago’s proprietary sigma-delta modulation technology to provide reinforced isolation between the input and output stages. The device features a fixed gain of 8, optimized for current sensing applications. It offers a high common-mode transient immunity (CMTI) of typically 50 kV/µs, ensuring reliable operation in noisy industrial environments. The input stage is designed for direct connection to shunt resistors, enabling accurate current measurement without external components. The output is a differential analog signal suitable for interfacing with analog-to-digital converters (ADCs). The ACPL-C870-000E operates from a single 5V supply and provides a specified isolation voltage of 5 kVrms for one minute per UL1577 and IEC/EN/DIN EN 60747-5-5.
