ina293a4idbvr.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 5 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

INA293A4IDBVR

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

INA293A4IDBVR 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. Buffered output equal to (VIN+ - VIN-) x Gain (200 V/V for the A4 variant). Swings from GND+0.005 V to Vs-0.07 V into a 10kΩ load.
2 GND power_in Device ground reference.
3 IN+ input Shunt resistor positive sense input. Connect to the high-side terminal of the external current-sense (shunt) resistor. Common-mode range -4 V to +110 V. Input bias current ~20 µA typical.
4 IN- input Shunt resistor negative sense input. Connect to the low-side terminal of the external current-sense (shunt) resistor. Common-mode range -4 V to +110 V. Input bias current ~20 µA typical.
5 Vs power_in Power supply, 2.7 V to 20 V (absolute max 22 V). Quiescent current 1.5 mA typical.

CAD (KiCad official)

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ina293a4idbvr-etched.step / ina293a4idbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ina293a4idbvr.step / ina293a4idbvr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ina293a4idbvr.step 85 KB You want the bare part, or you mark your own boards.
ina293a4idbvr-etched.step 2.1 MB You want the part with INA293A4IDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 546 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.
