The MCP39F511-E/MQ is a highly integrated Power-monitoring IC with calculation and energy accumulation. The complete single-phase power-monitoring IC designed for real-time measurement of input power for AC/DC power supplies and power distribution units. 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 10ppm/°C in addition to 94.5dB of SINAD performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
