ADUM3151ARSZ

Analog Devices · Digital Isolators · SSOP-20-208mil

ADUM3151ARSZ from Analog Devices, in a SSOP-20-208mil. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function

2 GND1 power_in Ground 1, the ground reference for isolator Side 1.
3 MCLK input SPI clock from the main controller.
4 MO input SPI data from the main MO/SI line.
5 MI output SPI data from the subordinate to the main MI/SO line.
6 MSS input Subordinate select from the main, active low logic; requires a 10 ns setup time from the next clock or data edge.
7 VIA input Low speed data input A.
8 VIB input Low speed data input B.
9 VOC output Low speed data output C.
10 GND1 power_in Ground 1, the ground reference for isolator Side 1.
11 GND2 power_in Ground 2, the ground reference for isolator Side 2.
12 VIC input Low speed data input C.
13 VOB output Low speed data output B.
14 VOA output Low speed data output A.
15 SSS output Subordinate select to the subordinate, active low logic.
16 SO input SPI data from the subordinate to the main MI/SO line.
17 SI output SPI data from the main to the subordinate MO/SI line.

Materials and finish

As the datasheet states them (page.json metadata.appearance; the 3D model's colours follow it).

Part Material Colour / plating Datasheet says Page
housing pC In accordance with DIN EN IEC 60747-17 (VDE 0884-17), each model is proof tested by applying an insulation test voltage ≥ 1059 V peak for 1 second (partial discharge detection limit = 5 pC). 9
