Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.++## Pinout++| Pin | Name | Type | Function |+|---|---|---|---|+| 1 | VDD1 | power_in | Primary-side supply voltage input, 3.0 V to 5.5 V. Powers the primary logic and the isoPower DC/DC oscillator. |+| 2 | GND1 | power_in | Primary-side reference ground. Internally tied to pin 8; both pins should be connected to the primary common ground. |+| 3 | VIA | input | Logic input for channel A (primary side). CMOS-level input to the forward isolation channel A. |+| 4 | VIB | input | Logic input for channel B (primary side). CMOS-level input to the forward isolation channel B. |+| 5 | VIC | input | Logic input for channel C (primary side). CMOS-level input to the forward isolation channel C. |+| 6 | VOD | output | Logic output for channel D on the primary side. Recovers the reverse-direction isolated digital signal from the secondary VID input. |+| 7 | RCOUT | output | Regulation control output. Connect to the RCIN pin of an isoPower slave device so that the ADuM5401 can regulate the slave's output voltage. |+| 8 | GND1 | power_in | Primary-side reference ground. Internally tied to pin 2; both pins should be connected to the primary common ground. |+| 9 | GNDISO | power_in | Isolated (secondary) side reference ground. Internally tied to pin 15; both pins should be connected to the isolated common ground. |+| 10 | VSEL | input | Output voltage select. Tie to VISO for a 5.0 V VISO regulation setpoint, or tie to GNDISO for a 3.3 V setpoint. |+| 11 | VID | input | Logic input for channel D on the secondary side. CMOS-level input to the reverse isolation channel D. |+| 12 | VOC | output | Logic output for channel C on the secondary side. Recovers the forward-direction isolated digital signal from primary VIC. |+| 13 | VOB | output | Logic output for channel B on the secondary side. Recovers the forward-direction isolated digital signal from primary VIB. |+| 14 | VOA | output | Logic output for channel A on the secondary side. Recovers the forward-direction isolated digital signal from primary VIA. |+| 15 | GNDISO | power_in | Isolated (secondary) side reference ground. Internally tied to pin 9; both pins should be connected to the isolated common ground. |+| 16 | VISO | power_out | Isolated secondary supply output from the integrated DC/DC converter. Regulated to 3.3 V or 5.0 V depending on VSEL; supplies the isolated data channels and external load (up to 500 mW total). |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Analog Devices |+| Package | SOIC-16-300mil |+| Category | Signal Isolation Devices |+| Pins | 16 |++## Ordering variants++Same part, different packaging or reel option.++- `ADUM5401ARWZ-RL`+- `ADUM5401ARWZ-RLCRWZ`+- `ADUM5401ARWZ-RLCRWZ-RL`++## CAD (KiCad official)++- Symbol: `ADUM5401ARWZ-RL`+- Footprint: `Package_SO:SOIC-16_3.9x9.9mm_P1.27mm`+- 3D model: SOIC-16-300mil (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Analog Devices datasheet](https://jlcpcb.com/api/file/downloadByFileSystemAccessId/8586194236757200896) (24 pp, sha256 `b8a49e2871ddd8e8`, retrieved 2026-08-17, tier: lcsc)+- **Datasheet language:** Chinese.
