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 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.
