Analog Devices, Inc. (NYSE: ADI), the market leader in energy
metering solutions, is introducing two families of single-chip
energy meter ICs that combine intelligent battery management and
ADI�s innovative signal processing technology to address the need
of the world�s electricity markets for feature-rich, highly
reliable meters. Increasingly, solid-state, failure-resistant
energy meters, such as those enabled by Analog Devices, are
replacing aging electro-mechanical systems by providing
consistently dependable measurement and new functions, like remote
meter-reading. ADI�s new ADE7100 and ADE7500 energy meter SoC
(system-on-chip) families include devices with intelligent battery
modes that allow the meters to maintain the time, sense temperature
changes, run the LCD (liquid crystal display) read-out, and perform
other critical system functions, while using at least 40 percent
less power than competitive solutions. Based on Analog Devices�
field-proven ADE energy measurement core, which has been designed
into more than 175 million energy meters worldwide, the highly
integrated SoC devices perform functions previously requiring as
many as six discrete ICs and further extend ADI�s portfolio of
industry-leading energy metering solutions. �For electricity meter
designers who require a better solution to the growing demand for
feature- rich, highly reliable LCD energy meters, the ADE7100 and
ADE7500 families provide an accurate, low-power and intelligently
integrated solution for single-phase energy meters,� said Lu Han
Xi, chief engineer at energy meter manufacturer Linyang Electronics
in China. �We look to Analog Devices� for leadership based on its
legacy of designing metering solutions that have excellent accuracy
and reliability.� Enabling Advanced Meter-reading, Billing, and
Load Shedding Services The ADE7100 and ADE7500 energy meter
families combine Analog Devices� proven energy measurement core
with a microprocessor, on-chip flash memory, LCD driver, real-time
clock (RTC) and intelligent battery management circuitry. The
result is a high-quality, cost-effective solution that is less
susceptible to system failures and enables advanced services like
remote meter-reading, time-of-use billing, which requires power
companies to measure energy consumption according to hourly use,
and load shedding, which is the act of cutting off the electric
current on certain lines when demand outstrips supply. �Analog
Devices� leadership position gives it a unique perspective on the
needs of our energy metering customers � both in terms of the
technology that gets them to market faster and at lower cost, as
well as the next-generation features that keep them competitive,�
said Pat O�Doherty, product line director, Precision Signal
Processing Group, Analog Devices. �The industry shipped over 100
million energy meters last year, and as that number continues to
climb, we believe the ADE7100 and ADE7500 families will meet the
growing requirements for efficient, highly integrated solutions.�
Ideal for Energy Meters with LCD Displays The highly integrated
ADE7100 and ADE7500 families provide an SoC solution for energy
meters with LCD-displays. The devices combine ADI�s metering core,
derived from the ADE7755, with intelligent battery management
circuitry consisting of an internal battery switch and a
stand-alone state machine. With a low battery-mode current
consumption of 1.2 microamps, the devices reduce power use by at
least 40 percent in battery mode compared to competitive solutions,
while still allowing the meters to maintain critical functions�such
as monitoring temperature and main supply voltage�during power
outages. The installation of energy meters with LCD displays
continues to accelerate globally. To address this trend, the
ADE7100 and ADE7500 families integrate an LCD driver that meets
industrial temperature specifications for all outdoor climate
conditions. On-chip charge-pumps controlled by a digital-to-analog
converter (DAC) allow designers to easily adjust LCD contrast by
setting the drive voltage up to 5.4V with a power supply of 3.3V,
which ensures the display is clearly visible even as temperature
ranges fluctuate between -40 degrees C to 85 degrees C. Analog
Devices� energy metering core includes active, reactive and
apparent energy calculations, as well as voltage and current rms
(root-mean-square) measurements. Several power supervisory
features, such as SAG detection, peak and zero crossing, are built
into the core to simplify energy meter design. The devices�
microprocessor includes a single-cycle 8052 core, an RTC with full
battery backup and a choice of a UART (universal asynchronous
receiver-transmitter), SPI (serial peripheral interface) or I2C
interface. The ADE7100 family of products feature a second current
input for tamper detection. Availability and Pricing Four products
in the ADE7100 (ADE7166, ADE7169) and ADE7500 (ADE7566, ADE7569)
families are sampling now with full production scheduled for
February 2007. The devices are available in 64-lead LQFPs
(low-profile quad flat packages) and are priced under $3.00 per
unit in 1,000-piece quantities. For more information, visit

Measurement With more than 175 million 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�
ADE energy metering ICs combine analog-to-digital converters (ADCs)
with fixed-function digital signal processors (DSPs) 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. Analog Devices� ADE ICs are ideal
for measuring watts (kWh), reactive energy (VAR), RMS and power
quality with the highest accuracy in single-phase and polyphase
revenue meters and industrial instruments. Analog Devices also
offers its proprietary brand of single- and polyphase energy
metering chipsets and DSP-based metering engines as complete,
licensable solutions. For more information, visit
