Microchip Technology Inc. (Chandler, AZ) has announced a new power monitoring IC, the MCP39F501. This device is a highly integrated, single-phase power- monitoring IC designed for real-time measurement of AC power. It includes two 24-bit delta-sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible two-wire interface. An integrated low-drift voltage reference in addition to 94.5 dB of SINAD performance on each measurement channel allows accurate designs with just 0.1% error across a 4000:1 dynamic range. Operating temperature range is from -40°C to +125°C.
