Description

The ACPL-796J is a 1-bit, second-order sigma-delta (-) modulator converts an analog input signal into a high-speed 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 of ACPL-796J 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. The signal information is contained in the modulator data, as a density of ones with data rate up to 20 MHz, and the data are encoded and transmitted across the isolation boundary where they are recovered 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 has a wide supply range of 3 V to 5.5 V.

The ACPL-796J's internal clock version modulators, HCPL-7860 (DIP-8/gull wing surface mount package) and HCPL-786J (SO-16 package), are also available.
