ACPL-C799 Datasheet Sigma-delta Modulator

Manufacturer: Broadcom

Overview: ACPL-C799 Optically Isolated ±50 mV Sigma-Delta Modulator Data.

General Description

The Avago Technologies’ ACPL-C799 is a 1-bit, second-order sigma-delta (-) modulator converts an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology.

The ACPL-C799 operates from a 5V power supply with dynamic range of 77 dB with an appropriate digital filter.

The differential inputs of ±50 mV (full scale ±80 mV) are ideal for direct connection to shunt resistors or other low-level signal sources in applications, such as motor phase current measurement.
