Description:

The MCP39F501 is a highly integrated, single-phase

power-monitoring IC designed for real-time

measurement of input power for AC/DC power

supplies, power distribution units 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.
