INA180A2IDBVR

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

INA180A2IDBVR 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. OUT = Gain x (V(IN+) - V(IN-)), Gain = 50 V/V for the A2 device. Swings from ~(GND+0.5 mV) to ~(VS-0.02 V) with a 10 kΩ load.
2 GND power_in Device ground reference (0 V).
3 IN+ input Current-sense amplifier positive input. For high-side sensing, connect to the bus-voltage side of the sense resistor; for low-side sensing, connect to the load side of the sense resistor. Common-mode range -0.2 V to +26 V, independent of VS.
4 IN- input Current-sense amplifier negative input. For high-side sensing, connect to the load side of the sense resistor; for low-side sensing, connect to the ground side. Common-mode range -0.2 V to +26 V. Differential
5 VS power_in Positive supply, 2.7 V to 5.5 V (absolute max 6 V). Bypass to GND with a 0.1 µF ceramic capacitor placed close to the pin.

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ina180a2idbvr-etched.step / ina180a2idbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina180a2idbvr.step / ina180a2idbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ina180a2idbvr.step 85 KB You want the bare part, or you mark your own boards.
ina180a2idbvr-etched.step 2.2 MB You want the part with INA180A2IDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 548 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.
