ACPL-7970 Optically Isolated Sigma-Delta Modulator Data Sheet Description The ACPL-7970 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-7970 operates from a 5 V power supply with dynamic range of 78 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 a means of sigma-delta over-sampling using an on-board clock.
