RS8051XF

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

RS8051XF 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 output stage; typical output swing to within 5 mV of rails with RL = 50 kOhm. Short-circuit current typ 30 mA.
2 V- power_in Negative supply / ground rail. Total supply (V+ to V-) range 1.4 V to 5.5 V (absolute max 7.0 V).
3 +IN input Non-inverting input. Rail-to-rail common-mode range -0.1 V to 5.6 V with Vs = 5.5 V. Input bias current 1 pA typ; diode-clamped to supplies (limit swing beyond rails to <=10 mA).
4 -IN input Inverting input. Rail-to-rail common-mode range -0.1 V to 5.6 V with Vs = 5.5 V. Input bias current 1 pA typ; diode-clamped to supplies.
5 V+ power_in Positive supply. Operating range 1.4 V to 5.5 V referenced to V-; absolute max V+ to V- = 7.0 V. Quiescent current 670 nA typ.

CAD (KiCad official)

  • Symbol: RS8051XF
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: rs8051xf-etched.step / rs8051xf-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs8051xf.step / rs8051xf.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
rs8051xf.step 85 KB You want the bare part, or you mark your own boards.
rs8051xf-etched.step 1.8 MB You want the part with RS8051XF already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 442 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 (10 pp, sha256 6d9dedaaaa62b332, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
