| Parameter | ||
|---|---|---|
| Supply voltage | - | 1.8V to 5V supplies; 3kV RMS isolation class. |
| Memory & Peripherals | - | The fail-safe suffix is the new decision: output state when the input side is unpowered - the old row fixed this behavior in silicon, the N row hands it to the orderable number. |
| Case | SOIC-8 (narrow body) | SOIC-8 |
| Compatibility Level | - | Pin-to-Pin (Minor Clock/Init Tuning) |
| Component Category | Digital Isolators (iCoupler) | - |
| Core & Architecture | - | The N-generation replacement documented as pin-compatible with the ADuM1201 (the ADuM120N1 maps to the ADuM1200): up to 150Mbps, lower propagation delay, 100kV/us common-mode transient immunity and selectable fail-safe output (N0 against N1). |
| Firmware Notes | - | The upgrade direction is calm: pin-compatible into the classic sockets with better performance. The one review: which fail-safe behavior the design assumed during power sequencing - check the N0/N1 suffix against the board behavior before standardizing. |
| Hardware Notes | - | Same SOIC-8 land pattern. |
| Lead Time Advantage | - | Shenzhen Spot Stock (24-48h Dispatch) |
| Market Reality | The ADuM120x pair is the digital isolator that replaced optocouplers across industrial designs: two channels on a magnetic barrier instead of an LED, 2.5kV of isolation in an eight-pin SOIC, supplies from 2.7V to 5.5V that made 3.3V-to-5V level translation and isolation one component. The naming is a single decision - ADuM1200 carries both channels in one direction, ADuM1201 is the 1/1 bidirectional part - and the generation upgrade is documented pin-for-pin: the N-family maps onto the classic sockets with faster rates and fail-safe output options. The substitution mistake in this family is one character wide and completely fatal to the signal path. | - |
