Product Summary

The CS5464-ISZ is an integrated power measurement device which combines three analog-to-digital converters, power calculation engine, energy-to-frequency converter, and a serial interface on a single chip. The CS5464-ISZ is designed to accurately measure instantaneous current and oltage and calculate VRMS, IRMS, instantaneous power, active power, apparent power, and reactive power for high-performance power measurement applications. The CS5464-ISZ is optimized to interface to shunt resistors or current transformers for current measurement, and to resistive dividers or potential transformers for voltage measurement.
