ACPL-C799 Optically Isolated ±50 mV Sigma-Delta Modulator Data Sheet 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.
The analog input is continuously sampled by a means of sigma-delta over-sampling using an on-board c...
