The original signal information can be reconstructed with a digital filter. The serial interface for data and clock has A wide supply range of 3V to 5.5V is offered in the serial interface for data and clock. The modulator, combined with superior optical-coupling technology, delivers high noise margins and excellent immunity against isolation-mode transients. The ACPL-C740 provides reliable reinforced insulation and high working insulation voltage with a 0.5mm minimum distance through insulation (DTI), making it suitable for fail-safe designs. The isolated ADC delivers the reliability, small size, superior isolation, and over-temperature performance that motor drive designers need to measure current accurately.
