Optically Isolated Sigma-Delta Modulators

23 DECEMBER 2008

Avago Technologies announced one of the industry’s first optically isolated sigma-delta modulator using an external clock to provide direct measurement of motor phase currents in power inverters. Based on an advanced low power CMOS process, the ACPL-796J uses an external clock that allows synchronized data conversion between the current sensor and controller to help motor control designers eliminate complex design processes in data and clock reading. Moreover, the ACPL-796J is designed with digital inputs and outputs that are compatible with systems powered by 5- or 3-volt supplies and works under a wide industrial temperature range. Offered in a 16-lead small outline package, the isolated A/D converter delivers the reliability, small size, superior isolation and over-temperature performance motor drive designers need to accurately measure current at a much lower price compared to traditional current transducers.
