Description

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.
