CS5463 - Cirrus Logic

CS5463 Single Phase / Bi-directional Power/Energy IC

The CS5463 is an integrated power measurement device which combines two  analog-to-digital converters, power calculation engine, energy-to-frequency converter, and a serial interface on a single chip. It is designed to accurately measure instantaneous current and voltage, and calculate VRMS, IRMS, instantaneous power, apparent power, active power, and reac.
