Description

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 10ppm/°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.
