Product Overview

The Broadcom ACPL-C797 is a 1-bit, second-order sigma-delta (-) modulator that converts an analog input signal into a high-speed data stream with galvanic isolation using optical coupling technology. It operates from a 5-V supply and offers an 80 dB dynamic range with an appropriate digital filter. The device features differential inputs ideal for direct connection to shunt resistors for applications like motor phase current measurement. With superior optical isolation and a 0.5-mm minimum distance through insulation (DTI), it provides reliable reinforced insulation and high working insulation voltage, suitable for fail-safe designs. Offered in a Stretched SO-8 (SSO-8) package, it delivers reliability, small size, and superior isolation performance for motor drive designers.
