INA168NA

Texas Instruments · Current-Sensing Amplifiers · SOT-23-5

INA168NA from Texas Instruments, in a SOT-23-5. 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 OUT output Output current. Sourced through an external load resistor R_L to GND to develop the output voltage V_O = I_S * R_S * R_L / 5 kΩ. Output impedance ~1 GΩ
2 GND power_in Device ground reference.
3 VIN+ input Positive differential sense input; connects to the high-voltage side of the external shunt resistor R_S. Common-mode range 2.7 V to 60 V (independent of V+).
4 VIN- input Negative differential sense input; connects to the load side of the external shunt resistor R_S. Full-scale sense voltage (VIN+ - VIN-) up to 500 mV.
5 V+ power_in Power supply input, 2.7 V to 60 V. Supply is independent of the input common-mode voltage. Quiescent current typically 25 µA.

CAD (KiCad official)

  • Symbol: INA168NA
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ina168na-etched.step / ina168na-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina168na.step / ina168na.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ina168na.step 85 KB You want the bare part, or you mark your own boards.
ina168na-etched.step 1.4 MB You want the part with INA168NA already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 357 faces against 102 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.

Provenance

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

  • Datasheet: Texas Instruments datasheet (28 pp, sha256 381c48493d9daa2e, retrieved 2026-08-17, tier: manufacturer)
  • 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).
