SGM321BYN5

SGMICRO · Operational Amplifier · SOT-23-5

SGM321BYN5 from SGMICRO, 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 Amplifier output. Rail-to-rail output swing; typical short-circuit source/sink current 84mA/75mA at Vs=5V into a 10Ω load.
2 -Vs power_in Negative supply rail (ground for single-supply operation). Total supply voltage +Vs to -Vs is 2.1V to 5.5V (6V absolute max).
3 +IN input Non-inverting input. Rail-to-rail input common-mode range (-0.1V to Vs+0.1V, or -0.1V to 5.6V at Vs=5.5V); typical input bias current 10pA.
4 -IN input Inverting input. Rail-to-rail input common-mode range; typical input bias current 10pA and input offset voltage 0.8mV typ / 5mV max.
5 +Vs power_in Positive supply rail. Operating range 2.1V to 5.5V single supply; quiescent current 60µA typ / 86µA max per amplifier.

Two STEP files. Same geometry, different body top:

File Size Use it when
sgm321byn5.step 85 KB You want the bare part, or you mark your own boards.
sgm321byn5-etched.step 2.0 MB You want the part with SGM321BYN5 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 489 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).
