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

ADUM5402ARWZ-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, 3.0 V to 5.5 V. Powers the input side of the isolator and the isoPower DC/DC primary.
2 GND1 power_in Primary side ground reference. Pin 2 and Pin 8 are internally connected; tie both to the primary common ground.
3 VIA input Logic input A. CMOS-level forward-channel A input on the primary side.
4 VIB input Logic input B. CMOS-level forward-channel B input on the primary side.
5 VOC output Logic output C. Reverse-channel C output on the primary side. VOH ≈ VDD1 - 0.3 V at IOx = -20 μA; VOL ≈ 0.0 V at IOx = 20 μA.
6 VOD output Logic output D. Reverse-channel D output on the primary side. VOH ≈ VDD1 - 0.3 V at IOx = -20 μA.
7 RCOUT output Regulation control output. Connects to the RCIN of an isoPower slave device to allow the ADuM5402 to control the slave's regulation function.
8 GND1 power_in Primary side ground reference. Internally connected to pin 2; tie both to the primary common ground.
9 GNDISO power_in Isolated (secondary) side ground reference. Pin 9 and Pin 15 are internally connected; tie both to the isolated common ground.
10 VSEL input Output voltage selection. Tie VSEL = VISO to set the VISO regulation setpoint to 5.0 V; tie VSEL = GNDISO to set the setpoint to 3.3 V.
11 VID input Logic input D. CMOS-level reverse-channel D input on the isolated side.
12 VIC input Logic input C. CMOS-level reverse-channel C input on the isolated side.
13 VOB output Logic output B. Forward-channel B output on the isolated side. VOH ≈ VISO - 0.3 V at IOx = -20 μA.
14 VOA output Logic output A. Forward-channel A output on the isolated side. VOH ≈ VISO - 0.3 V at IOx = -20 μA.
15 GNDISO power_in Isolated (secondary) side ground reference. Internally connected to pin 9.
16 VISO power_out Isolated secondary-side regulated power supply output for the isolated data channels and external load. Output is 3.3 V or 5.0 V depending on VSEL. Up to ~100 mA (5 V) or ~60 mA (3.3 V) drive.
