GS8332-SR

Gainsil · Precision OpAmps · SOP-8

GS8332-SR from Gainsil, in a SOP-8. 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 OUTA output Amplifier A output. Rail-to-rail swing (typ. within 5 mV of supply rails with RL=100 kOhm, 20 mV with RL=10 kOhm). Short-circuit current limit ~20 mA typ.
2 INA- input Amplifier A inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C.
3 INA+ input Amplifier A non-inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C.
4 VSS power_in Negative supply / ground. For single-supply operation tie to GND; for dual-supply operation typ. -0.9 V to -2.75 V. Decouple to VDD with 0.1 uF ceramic close to the pin.
5 INB+ input Amplifier B non-inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C.
6 INB- input Amplifier B inverting input. Rail-to-rail common-mode range (VSS-0.1 V to VDD+0.1 V). Input bias current typ. 20 pA @ 25 C.
7 OUTB output Amplifier B output. Rail-to-rail swing (typ. within 5 mV of supply rails with RL=100 kOhm, 20 mV with RL=10 kOhm). Short-circuit current limit ~20 mA typ.
8 VDD power_in Positive supply. 1.8 V to 5.5 V single-supply operating range (absolute max 7.5 V VDD-VSS). Bypass to VSS with a 0.1 uF ceramic close to the pin.

CAD (KiCad official)

  • Symbol: GS8332-SR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: gs8332-sr-etched.step / gs8332-sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8332-sr.step / gs8332-sr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gs8332-sr.step 122 KB You want the bare part, or you mark your own boards.
gs8332-sr-etched.step 2.5 MB You want the part with GS8332-SR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 593 faces against 147 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.
