GS8631-TR

Gainsil · Low Noise Amplifiers (LNA) - RF · SOT-23-5

GS8631-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 Op-amp output. Rail-to-rail output swing capable of driving 600 ohm loads; typical closed-loop output impedance 3 ohm and output current up to ~53 mA.
2 VSS power_in Negative supply / ground reference. Together with VDD forms the single-supply range of 2.1 V to 5.5 V (absolute max VDD-VSS = 7.5 V).
3 IN+ input Non-inverting analog input. Rail-to-rail common-mode range (typ -0.1 V to VDD+0.1 V); input bias current ~1 pA typ.
4 IN- input Inverting analog input. Rail-to-rail common-mode range (typ -0.1 V to VDD+0.1 V); input bias current ~1 pA typ.
5 VDD power_in Positive supply. Single-supply operation from +2.1 V to +5.5 V (absolute max VDD-VSS = 7.5 V). Quiescent current ~470 uA/amplifier at 5 V.

  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: gs8631-tr-etched.step / gs8631-tr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8631-tr.step / gs8631-tr.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Gainsil datasheet (19 pp, sha256 c17e6fe6cae0310b, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
