All four channels are forward-direction (side 1 to side 2), making it ideal for isolating unidirectional signal buses such as SPI (SCLK, MOSI, CS, and additional control). The device provides 2.5kV rms galvanic isolation per UL 1577 with minimum 25kV\/us common-mode transient immunity. Both sides operate from 2.7V to 5.5V, enabling level translation between different voltage domains. The RL suffix indicates tape and reel packaging.","working_principle":"The ADUM2401ARWZ-RL operates using iCoupler magnetic isolation technology. (1) Each of the four channels consists of a CMOS encoder on the input side that converts the digital input signal into high-frequency pulses driving on-chip planar transformer windings. The magnetic coupling transfers the signal across the isolation barrier to the secondary winding, where a CMOS decoder reconstructs the digital signal. (2) All four channels carry signals in the forward direction (VIA->VOA, VIB->VOB, VIC->VOC, VID->VOD), providing isolation for unidirectional signal paths. (3) The refresh circuit continuously pulses the transformers to maintain correct output state during static input conditions, and the high 25kV\/us CMTI prevents false switching during common-mode transient events.","pin_description":"
