SGM321XC5

SGMICRO · Operational Amplifier · SC-70-5

SGM321XC5 from SGMICRO, in a SC-70-5. 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 +IN input Non-inverting analog input. Rail-to-rail input common-mode range from -0.1V to (+Vs + 0.1V); ultra-low 10pA typical input bias current.
2 -Vs power_in Negative supply rail (or ground in single-supply operation). Total supply (+Vs to -Vs) 2.1V to 5.5V (6V absolute max).
3 -IN input Inverting analog input. Rail-to-rail input common-mode range; ultra-low 10pA typical input bias current.
4 OUT output Amplifier output. Rail-to-rail output swing (within 5mV of rails at RL=100kΩ, Vs=5V); source/sink capability 84mA/75mA typical into 10Ω to Vs/2.
5 +Vs power_in Positive supply rail. Operating range 2.1V to 5.5V referenced to -Vs; 60µA typical quiescent current per amplifier.

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm321xc5.step 87 KB You want the bare part, or you mark your own boards.
sgm321xc5-etched.step 2.0 MB You want the part with SGM321XC5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 471 faces against 102 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.

Provenance

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

  • Datasheet: SGMICRO datasheet (19 pp, sha256 95c3610d3cab472c, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
