ADUM5401ARWZ-RL

Analog Devices · Digital Isolators (With Power) · SOIC-16-300mil

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).
