The MCP39F511N is a highly integrated, dual-channel single-phase power-monitoring IC designed for real-time measurement of power for dual-socket wall outlets, power strips, AC/DC power supplies, and power distribution applications. It includes three ADCs for voltage and two current load measurements, a 16-bit calculation engine, EEPROM and a flexible 2-wire interface. An integrated low-drift voltage reference in addition to the 94.5 dB of SINAD performance on each current measurement channel allows for better than 0.5% accurate designs across a 4000:1 dynamic range.
