Next-Generation IC is Ideal for Electronic
Power-Measurement Applications
Delivers Accurate Power-Usage Measurements
The CS5461A enables digital power-meter
manufacturers to provide highly accurate,
cost-effective solutions for measuring
power usage. This new IC is an integrated
power-measurement device that combines
two Delta-Sigma A/D converters, high-
speed power calculation functions, and a
serial interface on a single chip. Additional
features include AC and DC calibration and
phase compensation. Designed for
residential single-phase or industrial three-
phase power-meter applications, the IC
accurately measures instantaneous current
and voltage while calculating instantaneous
power, real power, apparent power, I
and V

The CS5461A is easy to design in as
a pin-compatible upgrade to the popular
Cirrus Logic CS5460A. It retains all the
functionality of its predecessor, while also
providing an on-chip temperature sensor
which can be used to lower the
temperature coefficient, allowing for
higher accuracy over temperature. For
communication with a microcontroller,
the IC features a bi-directional serial
interface, which is initialized and fully
functional upon reset. The CS5461A can
interface to a low-cost shunt resistor or
transformer for current measurement and
to a resistive divider or potential
transformer for voltage measurement.
The CS5461A delivers accurate power
usage measurements and is ideal for
electronic power-meter applications.
