Broadcom Limited ACPL-C799-000E

Description
The ACPL-C799 is a 1-bit, second-order sigma-delta modulator that converts an analog input signal into a high-speed data stream with galvanic isolation based on optical coupling technology. It operates from a 5V power supply with a 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.
