ADUM1441ARQZ-RL7 Description

Short technical summary and product information.

The ADuM1441ARQZ-RL7 is a micropower, 4-channel digital isolator from Analog Devices, utilizing iCoupler technology for reliable signal isolation. It supports bidirectional communication with data rates up to 2 Mbps (NRZ).

This isolator family features ultralow power operation, with typical quiescent currents as low as 0.1 µA per channel when refresh is disabled at 2.5 V. Dynamic current consumption is also minimal, at 117 µA/Mbps per channel for 2.5 V operation. The device operates at high temperatures up to 125°C and provides high common-mode transient immunity exceeding 25 kV/µs.

Packaged in a compact 16-lead QSOP, the ADuM1441ARQZ-RL7 offers significant board space savings compared to larger isolation packages. It meets stringent regulatory requirements, including UL 1577 component recognition for 2500 V rms isolation and VDE certification.

Applications include general-purpose, low-power multichannel isolation, low-power peripheral interface (SPI) at 1 MHz, and 4 mA to 20 mA loop process controls. Its robust design and low power consumption make it suitable for various industrial and embedded systems requiring reliable signal isolation.
