ACPL-798J modulator equivalent, optically isolated sigma-delta modulator.
such as motor phase current measurement. The analog input is continuously sampled by means of sigma-delta over-sampling .
The ACPL-798J is a 1-bit, second-order sigma-delta (Σ-∆) modulator that oversamples an analog input signal into a highspeed data stream with galvanic isolation based on optical coupling technology. The ACPL-798J operates from a 5 V power supply with .
