The MCP39F521 is a highly integrated, complete single-phase power-monitoring device, 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 two-wire I2C interface. An integrated low-drift voltage reference with 10 ppm/°C in addition to 94.5 dB of signal-to-noise and distortion ratio (SINAD) performance on each measurement channel allows for better than 0.1% accurate designs across a 4000:1 dynamic range.
