ADUM1401ARWZ-RL

The maximum current per channel for the ADuM1400/ADuM1401/ADuM1402 isolators at 0 Mbps to 2 Mbps operation for 5 V is 1.0 mA .

The ADuM140x1 quad-channel digital isolators based on Analog Devices, Inc., iCoupler® technology provide outstanding performance characteristics superior to alternatives such as optocoupler devices. They eliminate the need for external drivers and other discrete components, consume one-tenth to one-sixth of the power of optocouplers at comparable signal data rates, and offer four independent isolation channels in various configurations and data rates. These isolators operate with a supply voltage ranging from 2.7 V to 5.5 V, providing compatibility with lower voltage systems and enabling voltage translation across the isolation barrier. Additionally, they provide low pulse width distortion and tight channel-to-channel matching. The ADuM140x1 isolators also have a patented refresh feature that ensures dc correctness in the absence of input logic transitions and when power is not applied to one of the supplies.

iCoupler devices differ from optocoupler devices in terms of design difficulties and power consumption. The iCoupler devices eliminate the need for external drivers and other discrete components, providing stable performance characteristics and consuming one-tenth to one-sixth of the power of optocouplers at comparable signal data rates .
