The ADUM1441ARQZ-RL7 is a four-channel digital isolator manufactured by Analog Devices / Maxim Integrated. It features magnetic coupling technology, providing galvanic isolation with a nominal voltage of 2500Vrms. The device supports a maximum data rate of 2 Mbps and has an operating temperature range of -40°C to 125°C. It is packaged in a 16-QSOP surface-mount package, suitable for PCB mounting in various electronic systems.
This digital isolator is used in applications requiring high-voltage isolation, such as industrial control systems, motor drives, and power supplies. Its unidirectional channel type and multiple inputs (3/1) configuration make it suitable for signal transmission where isolation and noise immunity are critical. The device's electrical characteristics include a propagation delay of approximately 180 ns, rise time of 2 ns, and pulse width distortion of up to 8 ns.
The device's quiescent current varies with supply voltage and refresh mode, with typical values of 5.6 µA per channel at 3.3V with refresh enabled, and 0.3 µA per channel with refresh disabled. It also exhibits typical dynamic current consumption of 148 µA/Mbps per channel at 3.3V. The package is designed for surface mounting, facilitating integration into compact electronic assemblies.
