The CS5461A 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, instantaneous power, apparent power, and active power for single-phase, 2- or3-wire power metering applications.
Features
