ACPL-C797T - Automotive Optically Isolated Sigma-Delta Modulator

General Description

The ACPL-C797T is a 1-bit, second-order sigma-delta (Σ-∆) modulator that converts an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology.

The ACPL-C797T operates from a 5 V power supply with dynamic range of 79 dB with an appropriate digital filter.

The differential inputs of ±200 mV (full scale ±320 mV) are ideal for direct connection to shunt resistors or other low-level signal sources in applications such as motor phase current measurement.
