Description

The CS5460 is a highly integrated ∆ Analog-to-Digital Converter (ADC) which combines two  ∆ 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, IRMS, and VRMS for single phase 2 or 3-wire power meter applica-tions. 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 fre-quency output that is proportional to energy. The product is initialized and fully functional upon power-up, and in-cludes facilities for system-level  calibration  under  control
of the user program.
