Avago Technologies announced the ACPL-C797 optically isolated sigma-delta ADC for current and voltage sensing in motor control and power generation applications. Features and specifications include a -40°C to +105°C operating temperature range, both 5 and 3,3 V compatible digital outputs, low offset voltage, a gain accuracy of ±1% and a ±10% accurate clock frequency. By implementing a digital filter in an FPGA, ASIC or DSP, the serial output is decoded to 12-bit effective resolution. In addition, the amplifier features 78 dB signal-to-noise ratio and minimises EMI with a slew rate controlled output. Available in a new Stretched SO-8 (SSO-8) package, the ACPL-C797’s printed circuit board footprint is 30% smaller than the traditional DIP-8.
