ACPL-C79A-500E with Optically Isolated Amplifiers Precision Iso-Amp is an industrial-grade, low-power, digitally-controlled, optically-isolated amplifier manufactured by Broadcom. It features a high common-mode transient immunity of 500 V/µs which allows it to work in high electrical noise environments, without the need for additional buffering. Its low voltage operation (3.3-5.5 V) and excellent linearity make it ideal for precision signal conditioning, current loop control, and precise voltage control. It is designed to meet requirements for safety, immunity, and reliability for many industrial applications, including automotive, factory automation, and medical equipment.
