RS622PXK

Jiangsu RUNIC Tech · Operational Amplifier · SOIC-8

RS622PXK from Jiangsu RUNIC Tech, in a SOIC-8. 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 OUTA output Output of amplifier A. Rail-to-rail output; typical output swing to within 40 mV of rail with RL = 2 kΩ; short-circuit current ~50 mA.
2 -INA input Inverting input of amplifier A. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V (Vs=5.5V: -0.1V to 5.6V). Input bias current 1 pA typ.
3 +INA input Non-inverting input of amplifier A. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current 1 pA typ.
4 V- power_in Negative supply / ground. In single-supply operation connect to GND; in split-supply operation connect to negative rail. Total supply (V+ minus V-) 2.5 V to 5.5 V, absolute max 7.0 V.
5 +INB input Non-inverting input of amplifier B. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current 1 pA typ.
6 -INB input Inverting input of amplifier B. Rail-to-rail input, common-mode range -0.1 V to (V+)+0.1 V. Input bias current 1 pA typ.
7 OUTB output Output of amplifier B. Rail-to-rail output; typical output swing to within 40 mV of rail with RL = 2 kΩ; short-circuit current ~50 mA.
8 V+ power_in Positive supply pin. Total supply (V+ minus V-) 2.5 V to 5.5 V (absolute maximum 7.0 V). A 0.1 uF bypass capacitor should be placed close to this pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs622pxk.step 122 KB You want the bare part, or you mark your own boards.
rs622pxk-etched.step 1.9 MB You want the part with RS622PXK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 474 faces against 147 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 (14 pp, sha256 59f6ab6a541a84c0, 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).
