CS5460 Datasheet PDF - Cirrus Logic

Description

●The CS5460 is a highly integrated ∆ΣAnalog-to-Digital Converter (ADC) which combines two ∆ΣADCs, 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 applications.
