ACPL-796J Optically Isolated Sigma-Delta Modulator Data Sheet Description The ACPL-796J is a 1-bit, second-order sigma-delta () modulator converts an analog input signal into a highspeed data stream with galvanic isolation based on optical coupling technology. The ACPL-796J operates from a 5 V power supply with dynamic range of 80 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. The analog input is continuously sampled by means of sigma-delta over-sampling using external clock, coupled across the isolation barrier, which allows synchronous operation with any digital controller.
