General Description

The Broad® ACPL-C740 is a 1-bit, second-order sigmadelta (-) modulator that converts an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology.

The ACPL-C740 operates from a 5V power supply with dynamic range of 86 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.

Key Features
