The CS5460A is a highly integrated power measurement
solution which combines two
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. The CS5460A features a
bi-directional serial interface for communication
with a microcontroller and a pulse output engine for
which the average pulse frequency is proportional
to the real power.
