The ACPL-C797T-000E is a 1-bit, second-order sigma-delta modulator that converts an analog input signal into a high-speed data stream throughintegration of galvanic isolation based on optical coupling technology. The ACPL-C797uses a 5 V power supply with dynamic range of 80 dBand 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 continuouslymeasured by the sigma-delta modulator by over-sampling using an on-board clock. The signal information is contained in the modulator data, as a density of ones with data rate of 10 MHz.Datais then encoded and transmitted across the isolation boundary whereit isrecovered and decoded into high-speed data stream of digital ones and zeros. The original signal information can be reconstructed with a digital filter. The serial interface for data and clock has a wide supply range of 3 V to 5.5 V.Combined with superior optical coupling technology, the modulator delivers high noise margins and excellent immunity against isolation-mode transients. With 0.5 mm minimum distance through insulation (DTI), the ACPL C797 provides reliable reinforced insulation and high working insulation voltage, which is suitable for fail-safe designs. This isolation performance is superior to alternatives including devices based on capacitive- or magnetic-coupling with DTI in micro-meter range. Offered in a SO-16 package, the isolated ADC delivers the reliability, small size, superior isolation and over-temperature performance motor drive designers need to accurately measure current. This design alternativedelivers alower price when compared to traditional current transducers.An external clock version modulator ACPL-796J (SO-16 package) is also available.
