用51驱动CS5463 可以测量各种参数 -The CS5463 is an integrated power measurement

device which combines two ΔΣ

analog-to-digital converters, power calculation

engine, energy-to-frequency converter, and a

serial interface on a single chip. It is designed to

accurately measure instantaneous current and

voltage, and calculate VRMS, IRMS, instantaneous

power, apparent power, active power, and

reactive power for single-phase, 2- or 3-wire

power metering applications.

The CS5463 is optimized to interface to shunt resistors

or current transformers for current

measurement, and to resistive dividers or potential

transformers for voltage measurement.

The CS5463 features a bi-directional serial interface

for communication with a processor and a

programmable energy-to-pulse output function.

Additional features include on-chip functionality

to facilitate system-level calibration, temperature

sensor, voltage sag detection, and phase

compensation.
