The MCP39F511T-E/MQ from Microchip Technology is surface mount, highly integrated, complete single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies, power distribution units, consumer and industrial applications. It includes dual-channel Delta-Sigma ADCs, a 16-bit calculation engine, EEPROM and a flexible 2-wire interface. An integrated low-drift voltage reference with 10 ppm/°C in addition to 94.5 dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range. The MCP39F511T-E/MQ operates at voltage range from 2.7 V to 3.6 V and comes in 28-QFN (5x5) package. Operating temperature range is from -40°C to 125°C.
