ACPL-C79A-500E – AVAGO

The ACPL-C79A-500E is a galvanically isolated operational amplifier manufactured by Avago Technologies, housed in a standard 8-pin small outline (SO) package. It incorporates Avago’s proprietary sigma-delta modulation technology to provide reinforced isolation of the analog input signal. The device features a high common-mode transient immunity (CMTI) of typically 50 kV/µs, ensuring accurate signal transfer in noisy environments. The ACPL-C79A-500E offers a fixed gain of 8 and is designed for voltage sensing in power conversion applications, such as motor drives and renewable energy inverters. Its key specifications include a wide operating temperature range, low input offset voltage, and excellent linearity, enabling precise and reliable measurement of high-voltage signals. The isolation barrier is certified to industry safety standards, providing robust protection against high-voltage transients and ground loops.
