RS6331XF

Jiangsu RUNIC Tech · Operational Amplifier · SOT-23-5

RS6331XF from Jiangsu RUNIC Tech, 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; short-circuit current typ 55mA; output swing typ 25mV from rail with RL=2k.
2 V- power_in Negative supply / ground rail. For single-supply operation tie to GND. Total supply (V+ to V-) 2.5V to 5.5V, absolute max 7.0V.
3 +IN input Non-inverting op-amp input. Rail-to-rail input, common-mode range -0.1V to (V+)+0.1V (Vs=5.5V spec: -0.1V to 5.6V). Input bias current typ 1pA.
4 -IN input Inverting op-amp input. Rail-to-rail input; input terminals are diode-clamped to the supply rails, current-limit external drive beyond rails to <=10mA.
5 V+ power_in Positive supply. 2.5V to 5.5V single-supply, or split-supply +/-1.25V to +/-2.75V. Quiescent current typ 58uA/amplifier. Place a 0.1uF bypass cap close to this pin.

Two STEP files. Same geometry, different body top:

File Size Use it when
rs6331xf.step 85 KB You want the bare part, or you mark your own boards.
rs6331xf-etched.step 1.9 MB You want the part with RS6331XF already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 447 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: Jiangsu RUNIC Tech datasheet (18 pp, sha256 631d1d87ce16e5f5, 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).
