It provides galvanic isolation up to 3750Vrms between two supply domains, with two channels going each direction (2/2 input-side/side-2 configuration). The 1Mbps data rate suits general-purpose isolation tasks in industrial control, motor drives, PLC I/O modules, and isolated sensor interfaces where signal integrity and noise rejection matter more than multi-megabit throughput. ## Key ratings that decide the fit The 3750Vrms isolation rating is the headline spec for safety-barrier applications — it meets basic reinforced isolation requirements for many industrial and medical systems. The 25kV/µs common-mode transient immunity (CMTI) means this part can reject fast voltage spikes across the isolation barrier, which is critical in motor-drive environments where PWM switching injects high dv/dt into the ground plane. Propagation delay is 100ns max each direction, with 40ns pulse-width distortion — tight enough for most control-loop feedback paths but not for high-speed digital buses like SPI at 10MHz. ## Supply voltage and logic compatibility Supply range spans 2.7V to 5.5V on both sides, so the ADUM1412ARWZ works directly with 3.3V and 5V logic families without external level shifters. This is a practical advantage when bridging a 3.3V microcontroller domain to a 5V sensor or actuator interface — the same part handles both rails. The unidirectional channel architecture means each data direction has dedicated paths, avoiding the bus-turnaround logic needed with bidirectional isolators. ## Package and mounting The wide-body SOIC provides adequate creepage distance for the 3750Vrms rating. No isolated power output — this is a signal-only isolator; the secondary-side supply must come from the board's own rail. The extended range also covers most HVAC and building-automation enclosures. ## Lifecycle and sourcing posture ROHS3 compliant.","metaTitle":"ADUM1412ARWZ iCoupler Digital Isolator, 4-Ch, 1Mbps","metaDescription":"ADUM1412ARWZ general-purpose digital isolator with 4 unidirectional channels, 1Mbps data rate, 3750Vrms isolation, and -40°C to 105°C range.
