Analog Devices Introduces the Industry’s Lowest Power Digital Isolators

The ADuM144x family of iCoupler® digital
isolators reduces power by a factor of 1,000 compared to
optocouplers to improve energy efficiency and comes in the
industry’s smallest package
Analog Devices (NASDAQ: ADI) introduced today the ADuM144x
family, the industry’s lowest power digital isolators. Based on
ADI’s proprietary iCoupler technology, the ADuM144x can be powered
by as little as 1 μW of power, delivering power levels over 1,000
times lower than optocouplers and competing digital isolators. At
these levels the ADuM144x family is ideally suited for industrial
and instrumentation systems such as 4-20 mA current loops, remote
sensors and green systems that demand high energy efficiency or
depend on limited power sources, such as batteries. Watch this

evaluation boards.
The ADuM144x are quad-channel data isolators available in three
different channel configurations with a one-minute isolation safety
rating of 2.5 kV rms. They have an operating voltage range of 2.25
V to 3.6 V, further reducing power constraints and providing the
lowest isolator operating voltage on the market. Quiescent power
supply current at 2.5 V is less than 5 μA per channel, and power
supply current at 2 Mbps is less than 380 μA per channel. A power
saving mode can reduce current levels to as little as 0.1 μA per
channel, resulting in an industry-best 1 μW of total power for the
entire isolator. In addition to the significant power savings, the
ADuM144x is also available in a 16-lead QSOP package, making it the
industry’s smallest quad-channel digital isolators with a 2.5 kV
rms isolation rating.
“The ADuM144x is a natural extension of our iCoupler digital
isolator product family which includes the highest performance,
most reliable isolators on the market. With the industry’s
increased focus on energy efficiency, we recognized that our core
iCoupler technology was the only isolation technology on the market
capable of achieving such low power levels. We worked with
customers to define this breakthrough product family and enhance
our capabilities to serve their system needs,” said David Krakauer,
product line manager of Analog Devices’ isolation and interface
product line.
The ADuM144x family employs the same iCoupler chip-scale
transformer technology used in ADI’s full line of safety isolation
products and used in the more than one billion channels of
isolation shipped in over ten years. The ADuM144x in the 16-lead
QSOP package is in production and available today with versions in
different packages, channel counts and higher isolation ratings
forthcoming.
