CS5460A-BS

电流和电力监控器、调节器 Single-Phase Bi-Dir Power/Energy IC

Description

The CS5460A is a highly integrated power measurement solution which combines two  ∆Σ Analog-to-digital Converters ADCs, high-speed power calculation functions, and a serial interface on a single chip. It is designed to accurately measure and calculate: Real True Energy, Instantaneous Power, IRMS, and VRMS for single phase 2- or 3-wire power metering applications. The CS5460A interfaces to a low-cost shunt resistor or transformer to measure current, and to a resistive divider or potential transformer to measure voltage.
