GS321A-TR

Gainsil · Operational Amplifier · SOT-23-5

GS321A-TR from Gainsil, in a SOT-23-5. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN+ input Non-inverting input; rail-to-rail input common-mode range extends from VSS-0.1V to VDD+0.1V.
2 VSS power_in Negative supply (ground in single-supply operation); for dual supplies bypass to ground with a 0.1µF ceramic capacitor.
3 IN- input Inverting input; rail-to-rail input common-mode range extends from VSS-0.1V to VDD+0.1V.
4 OUT output Rail-to-rail amplifier output, optimized for bandwidth rather than driving capacitive loads.
5 VDD power_in Positive supply for 2.1V to 5.5V operation (absolute maximum 7.5V to VSS); place a 0.1µF ceramic bypass capacitor close to this pin.

CAD (KiCad official)

  • Symbol: GS321A-TR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: gs321a-tr-etched.step / gs321a-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs321a-tr.step / gs321a-tr.glb are the bare package body.
