INA180A1IDBVR

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

INA180A1IDBVR 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 Analog output voltage. Amplified representation of the differential sense-resistor voltage; output = Gain (20 V/V for A1) x (V(IN+) - V(IN-)). Swings within the V_S rail.
2 GND power_in Ground reference for the device. Connect to system ground.
3 IN+ input Current-sense amplifier positive input. For high-side applications, connect to bus-voltage side of the sense resistor; for low-side applications, connect to load side of the sense resistor. Common-mode range -0.2 V to +26 V.
4 IN- input Current-sense amplifier negative input. For high-side applications, connect to load side of the sense resistor; for low-side applications, connect to ground side of the sense resistor. Common-mode range -0.2 V to +26 V.
5 VS power_in Positive supply voltage, 2.7 V to 5.5 V (recommended). Bypass with a 0.1 uF capacitor close to the pin.

CAD (KiCad official)

  • Symbol: INA180A1IDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ina180a1idbvr-etched.step / ina180a1idbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina180a1idbvr.step / ina180a1idbvr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ina180a1idbvr.step 85 KB You want the bare part, or you mark your own boards.
ina180a1idbvr-etched.step 2.0 MB You want the part with INA180A1IDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 528 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.
