Analog Devices, Inc., (ADI) a
global leader in high-performance semiconductors for signal processing
applications, today introduced the industry’s first fully isolated A/D converter
designed for polyphase energy metering applications. The
ADE7913
3-channel, sigma-delta A/D converter incorporates Analog
Devices’ patented iCoupler® and isoPower® technologies to implement isolated
signal transfer and dc-to-dc power conversion across a 5kV-rated insulation
barrier. This enables the use of shunt resistor sensing elements instead of
current transformers (CTs), thereby providing immunity to magnetic field
interference and tampering. The use of shunts instead of CTs also reduces system
cost and size.

“In the past, polyphase meter
manufacturers had to decide between CT-based architectures vulnerable to
external magnetic fields, or discrete component shunt-based architectures
involving excessive complexity and functionality compromises,” said Ronn Kliger,
director for the Energy Group, Analog Devices. “Now, with an integrated
component incorporating synchronized A/D conversion and galvanic isolation, our
customers can develop feature-rich, cost-effective metrology solutions that are
completely immune to magnetic interference.”

Making a Difference for Energy
Metering Customers
With nearly half a billion energy meters using ADI’s
technology deployed worldwide, Analog Devices has delivered more energy
measurement solutions than any other semiconductor company. Superior in quality,
reliability, and performance, Analog Devices’ energy-metering ICs combine ADCs
(analog-to-digital converters) with fixed-function DSPs (digital signal
processors) to perform critical measurements, while providing unparalleled
functionality and ease-of-use.
Analog Devices offers a broad
range of semiconductor solutions that solve design challenges in every aspect of
metering systems, including energy measurement; data and power management; user
interface; and RF, GSM/GPRS, and power-line carrier communication solutions. For
