Digi-Key Corp andMouser Electronics are stocking inventory of both silicon and 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
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.
