ADI Energy Segment Overview

Analog Devices leads the industry in highly accurate and precise signal measurement and control by delivering cost competitive, high quality ICs for reliable

metering, measurement, and control. These products are used in renewable energy, electrical power transmission, and distribution applications, as well

as electric, gas, and water metering. The combination of ADI’s proven expertise in optimized system-level signal processing performance and its extensive

range of product offerings provides developers with accurate, reliable, and easy to design energy management solutions.

Main Challenges and System

Considerations

• Higher reliability and lower assembly/

manufacturing costs

• Relatively harsh environment with

temperatures up to +125°C

• Power conversion efﬁciency is critical and

components that consume as little power

as possible are needed

• Keeping the generated harmonics below the

regulatory levels

• Maintain low dc injection current levels onto

the grid

Why Choose ADI?

• ADI’s expertise in integrated energy

measurement—300 million ADI metrology-

based meters deployed

• 50% of all electrical grid equipment world-

wide uses ADI converters

• Precision measurement of current and

voltage through highly accurate converters

and ampliﬁers

• Enabling power networks using high perfor-

mance processing technology engineered

with robustness and reliability

• Mixed-signal conversion and processing

enable ease of design and reduced time

to market

Solar PV Application Categories
