Description
The CS5463 is an integrated power measure ment device which combines two  ∆Σ 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, instanta neous power, apparent power, active power, and reactive power for single-phase, 2- or 3-wire power metering applications.
