The ADuM1441ARSZ from Analog Devices is a micropower, 4-channel digital isolator utilizing iCoupler® technology. It combines high-speed CMOS and monolithic transformer technologies for superior performance compared to optocoupler devices.
This isolator supports up to a 2 Mbps data rate (NRZ) and features high common-mode transient immunity of over 25 kV/µs. It operates across a wide temperature range of -40°C to 125°C. The device provides 3750Vrms of isolation and is available in a 20-lead SSOP package.
Key electrical characteristics include ultralow power operation, with typical quiescent currents as low as 0.1 µA per channel (refresh disabled) at 2.5 V. Dynamic current consumption is typically 117 µA/Mbps per channel at 2.5 V. The device is suitable for general-purpose, low-power multichannel isolation applications, including low-power peripheral interface (SPI) and 4 mA to 20 mA loop process controls.
The ADUM1441ARSZ is designed for surface mount applications and comes in a compact 20-SSOP package, offering significant board space savings. It meets regulatory requirements such as UL 1577 and CSA Component Acceptance Notice 5A.
