Description

The MCP39F511N is a highly integrated, complete

dual-channel

single-phase

power-monitoring

IC

designed for real-time measurement of input power for

dual-socket wall outlets, power strips, and consumer

and industrial applications. It includes dual-channel

24-bit

Delta-Sigma

ADCs

for

dual-current

measurements, a 10-bit SAR ADC for voltage

measurement, a 16-bit calculation engine, EEPROM

and a flexible two-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

allow for better than 0.5% accurate designs across a

4000:1 dynamic range.
