ADUM5401ARWZ-RL from Analog Devices, in a SOIC-16-300mil. 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). |
