Analog Devices · Digital Isolators · SOIC-8

ADUM320N0WBRIZ-RL from Analog Devices, in a SOIC-8. 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
1 VDD1 power_in Supply voltage for isolator side 1, operating from 2.25 V to 5.5 V, and requires a 0.1 µF bypass capacitor.
2 VIA input Logic input A for channel A; when the side 1 supply is unpowered this input must be held low to avoid powering the device through its ESD protection circuitry.
3 VIB input Logic input B for channel B; when the side 1 supply is unpowered this input must be held low to avoid powering the device through its ESD protection circuitry.
4 GND1 power_in Ground reference for isolator side 1.
5 GND2 power_in Ground reference for isolator side 2.
6 VOB output Logic output B on the side 2 supply domain, with its high level set by VDD2.
7 VOA output Logic output A on the side 2 supply domain, with its high level set by VDD2.
8 VDD2 power_in Supply voltage for isolator side 2, operating from 2.25 V to 5.5 V, and requires a 0.1 µF bypass capacitor.
