ADUM3201ARZ

Analog Devices · Digital Isolators · SOIC-8

ADUM3201ARZ 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, which must be 2.7 V to 5.5 V for the ADuM3201A grade, referenced to GND1.
2 VOA output Logic output A on side 1 of the ADuM3201, driven from the isolated channel A input (VIA, pin 7).
3 VIB input Logic input B on side 1 of the ADuM3201, which must stay within 0 V to VDD1 (VIL/VIH thresholds are 0.3 VDD1 and 0.7 VDD1).
4 GND1 power_in Ground 1, the ground reference point for the isolator side 1 supply and signals.
5 GND2 power_in Ground 2, the ground reference point for the isolator side 2 supply and signals.
6 VOB output Logic output B on side 2 of the ADuM3201, driven from the isolated channel B input (VIB, pin 3).
7 VIA input Logic input A on side 2 of the ADuM3201, which must stay within 0 V to VDD2 (VIL/VIH thresholds are 0.3 VDD2 and 0.7 VDD2).
8 VDD2 power_in Supply voltage for isolator side 2, which must be 2.7 V to 5.5 V for the ADuM3201A grade, referenced to GND2.
