gs8331-tr.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

GS8331-TR

Gainsil · Precision OpAmps · SOT-23-5

GS8331-TR from Gainsil, 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 Amplifier output. Rail-to-rail output stage swings to within ~5 mV of either supply rail with a 100 kΩ load and ~20 mV with 10 kΩ. Short-circuit current typ. 20 mA (source and sink).
2 VSS power_in Negative supply / ground. Tie to GND for single-supply operation (VDD 1.8V-5.5V) or to the negative rail for dual-supply operation (±0.9V to ±2.75V). Bypass to VDD with a 0.1 µF ceramic capacitor placed close to the pin.
3 IN+ input Non-inverting analog input. Common-mode input range extends 100 mV beyond the supply rails (VSS-0.1V to VDD+0.1V). Absolute maximum input range is VSS-0.5V to VDD+0.5V.
4 IN- input Inverting analog input. Common-mode input range extends 100 mV beyond the supply rails (VSS-0.1V to VDD+0.1V). Input bias current typ. 20 pA at 25°C.
5 VDD power_in Positive supply. Single-supply operation from +1.8V to +5.5V (absolute max +7.5V referenced to VSS). Bypass to VSS with a 0.1 µF ceramic capacitor placed close to the pin.

  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: gs8331-tr-etched.step / gs8331-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8331-tr.step / gs8331-tr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gs8331-tr.step 85 KB You want the bare part, or you mark your own boards.
gs8331-tr-etched.step 2.0 MB You want the part with GS8331-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 480 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
