Cirrus CS5467-ISZ 4-Channel, Single Phase Power/Energy IC SSOP28

Manufactured by Cirrus Logic - SSOP28 SMD Package

DESCRIPTION

The CS5467 IC for digital power meters and energy measurement applications is designed for market-specific demands within Japan. It is an integrated power measurement device which combines three Delta-Sigma analog-to-digital converters, power calculation engine, energy-to-frequency converter and a serial interface into a single integrated circuit. It accurately measures instantaneous current and voltage and calculates V_RMS, I_RMS, instantaneous power and average power (active/reactive/apparent) for high-performance power measurement applications. In addition, the CS5467 features two current channels and two voltage channels for simultaneous two-phase measurements. This configuration is popular in network meters and commercial three-phase metering applications throughout the world.
