The MCP39F511 is a 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.
