GS8332-MR

Gainsil · Precision OpAmps · MSOP-8

GS8332-MR from Gainsil, in a MSOP-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 push-pull output; swings within ~5 mV of the supply rails into 100 kohm and within ~20 mV into 10 kohm. Short-circuit limited to ~20 mA typ (15 mA min) source/sink.
2 INA- input Amplifier A inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA.
3 INA+ input Amplifier A non-inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA.
4 VSS power_in Negative supply / ground. Single-supply operation ties this to GND; dual-supply operation ties this to the negative rail. Bypass with 0.1 uF close to the pin in dual-supply designs. Absolute maximum Vdd-Vss = 7.5 V.
5 INB+ input Amplifier B non-inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA.
6 INB- input Amplifier B inverting input. High-impedance CMOS input with rail-to-rail common-mode range (Vss-0.1 V to Vdd+0.1 V). Typical input bias current 20 pA.
7 OUTB output Amplifier B output. Rail-to-rail push-pull output; swings within ~5 mV of the supply rails into 100 kohm and within ~20 mV into 10 kohm. Short-circuit limited to ~20 mA typ (15 mA min) source/sink.
8 VDD power_in Positive supply. Single-supply range +1.8 V to +5.5 V (dual-supply +/-0.9 V to +/-2.75 V). Bypass with a 0.1 uF ceramic close to the pin. Absolute maximum Vdd-Vss = 7.5 V.

CAD (KiCad official)

  • Symbol: GS8332-MR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: gs8332-mr-etched.step / gs8332-mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8332-mr.step / gs8332-mr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
gs8332-mr.step 123 KB You want the bare part, or you mark your own boards.
gs8332-mr-etched.step 2.4 MB You want the part with GS8332-MR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 563 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.
