ADUM1201AR

Tokmas · Digital Isolators · SOIC-8

ADUM1201AR from Tokmas, in a SOIC-8. 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 Supply voltage for isolator Side 1. Operating range 3.0 V to 5.5 V referenced to GND1. Decouple locally to GND1 (typ. 0.1 uF).
2 VOA output Logic Output A. Side 1 output of the reverse-direction isolation channel A. CMOS-level output referenced to VDD1/GND1, drive capability ±10 mA absolute max, VOH >= VDD1-0.1 V at -20 uA.
3 VIB input Logic Input B. Side 1 input of the forward-direction isolation channel B. CMOS-level input referenced to VDD1/GND1; VIH >= 0.7VDD1, VIL <= 0.3VDD1.
4 GND1 power_in Ground reference for isolator Side 1. Return for VDD1, VOA and VIB.
5 GND2 power_in Ground reference for isolator Side 2. Return for VDD2, VOB and VIA. Isolated from GND1 across the barrier.
6 VOB output Logic Output B. Side 2 output of the forward-direction isolation channel B. CMOS-level output referenced to VDD2/GND2, VOH >= VDD2-0.1 V at -20 uA, drive ±10 mA absolute max.
7 VIA input Logic Input A. Side 2 input of the reverse-direction isolation channel A. CMOS-level input referenced to VDD2/GND2; VIH >= 0.7VDD2, VIL <= 0.3VDD2.
8 VDD2 power_in Supply voltage for isolator Side 2. Operating range 3.0 V to 5.5 V referenced to GND2. Decouple locally to GND2 (typ. 0.1 uF).

  • Symbol: ADUM1201AR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: adum1201ar-etched.step / adum1201ar-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adum1201ar.step / adum1201ar.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Tokmas datasheet (15 pp, sha256 b165d20985218836, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
