Product Summary
The CS5460A-BSZ is a highly integrated power measurement solution which combines two ΔΣ 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-BSZ interfaces to a low-cost shunt resistor or transformer to measure current, and to a resistive divider or potential transformer to measure voltage. The CS5460A-BSZ features a bi-directional serial interface for communication with a micro-controller and a pulse output engine for which the average pulse frequency is proportional to the real power. The CS5460A-BSZ has on-chip functionality to facilitate AC or DC system-level calibration.
