Analog Devices has introduced 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.
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.
