CS5460

www.DataSheet4U.com CS5460 Single Phase Bi-Directional Power/Energy IC Features l Energy Description The CS5460 is a highly integrated ∆Σ Analog-to-Digital Converter (ADC) which combines two ∆Σ ADCs, high speed power calculation functions, and a serial interface on a single chip. It is designed to accurately measure and calculate: Energy, Instantaneous Power, I RMS, and VRMS for single phase 2 or 3-wire power meter applications. The CS5460 interfaces to a low cost shunt or transformer to measure current, and resistive divider or transformer to measure voltage. The CS5460 features a bi-directional serial interface for communication with a micro-controller and a fixed-width programmable frequency output that is proportional to energy. The product is initialized and fully functional upon power-up, and includes facilities for system-level calibration under control of the user program.
