Industry’s First Digital Isolators Qualified for Automotive Systems
The ADuM120xW, ADuM130xW, and ADuM140xW families are the first digital isolators to
carry an AEC-Q100 qualified –40°C to +125°C automotive temperature rating meeting the
reliability and quality needs of emerging electric-hybrid vehicles. These families are based
on ADI’s award-winning
iCoupler
®
technology, which is currently employed in over 150
million channels of isolation.
The ADuM120xW, ADUM130xW, and ADuM140xW families of digital isolators are an
alternative solution to other isolation technologies, such as optocouplers.
iCoupler
digital
isolators are relatively insensitive to temperature and demonstrate excellent long-term
reliability. Where optocouplers suffer from performance degradation and wear-out at high
temperatures, the ADuM120xW, ADuM130xW, and ADuM140xW families have undergone
extended test coverage and high temperature testing allowing them to be qualified for
under-the-hood operation up to 125°C. In addition to reliability and temperature, the
iCoupler
devices consume one-tenth to one-sixth the power of optocouplers at comparable
data rates with a low power consumption rate of 3.5 mA/channel.

The newest members to the growing
iCoupler
portfolio provide designers with dual, triple, and quad configurations. With multiple
performance grades offered, these families also offer 3.0 V to 5.5 V voltage level translation. Available in 8-lead and 16-lead SOIC
packages, the versatility of these AEC-Q100 qualified devices can be used in a variety of automotive applications.
The ADuM120xW, ADuM130xW, and ADuM140xW families can be used in a number of ways within the rising electric-hybrid vehicle
industry. Applications include: battery monitoring, gate drive for hybrid electric motor, dc-to-ac inverters for various systems,
and electronic power steering. In addition to the benefits they provide in hybrid applications, the new devices can be used as an
interface for sensor clusters in all vehicles, eliminating concerns about ground loops and allowing for flexible placement of the
sensor clusters.
This extension of the
iCoupler
portfolio demonstrates ADI’s continued commitment to providing innovative solutions that are tailored
for application needs and that reduce the overall size, cost, and time to market.
