GS8538-SR

Gainsil · Precision Op Amps · SOP-8

GS8538-SR from Gainsil, in a SOP-8. 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 OUTA output Channel A amplifier output, rail-to-rail.
2 INA- input Channel A inverting input; input range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
3 INA+ input Channel A non-inverting input; input range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
4 VSS power_in Negative supply (ground in single-supply operation); VDD to VSS operating range is 2.0V to 5.5V.
5 INB+ input Channel B non-inverting input; input range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
6 INB- input Channel B inverting input; input range extends 100mV beyond the supply rails (VSS-0.1V to VDD+0.1V).
7 OUTB output Channel B amplifier output, rail-to-rail.
8 VDD power_in Positive supply, 2.0V to 5.5V single supply (absolute max 7.5V to VSS); bypass with a 0.1uF ceramic capacitor close to the pin.

CAD (KiCad official)

  • Symbol: GS8538-SR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: gs8538-sr-etched.step / gs8538-sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); gs8538-sr.step / gs8538-sr.glb are the bare package body.
