ACPL-C87AT-500E – AVAGO

The ACPL-C87AT-500E is a galvanically isolated operational amplifier manufactured by Avago Technologies, housed in a standard 8-pin small outline (SO-8) package. This device integrates a high-performance operational amplifier with Avago’s proprietary optical isolation technology, providing reinforced insulation rated for a working voltage of up to VIORM = 891 Vpeak per IEC/EN/DIN EN 60747-5-5. The isolation barrier allows for accurate amplification of signals in high common-mode voltage environments, preventing ground loops and protecting sensitive circuitry. Key specifications include a typical input offset voltage of ±0.5 mV, input bias current of ±10 nA, and a gain bandwidth product of approximately 2 MHz. The device is designed for applications requiring precise current and voltage sensing, such as motor control, power inverters, and isolated analog front-ends, where safety isolation and high accuracy are critical.
