Jiangsu RUNIC Tech · Precision OpAmps · SOIC-8

RS8552XK 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 OUT A output Output of amplifier A. Rail-to-rail CMOS output, short-circuit current typ. 50 mA, slew rate 2.7 V/µs, gain-bandwidth product 4.5 MHz.
2 -IN A input Inverting input of amplifier A. High-impedance CMOS input; input bias current typ. 50 pA; common-mode range extends 0.1 V beyond each supply rail.
3 +IN A input Non-inverting input of amplifier A. High-impedance CMOS input; input bias current typ. 50 pA; rail-to-rail common-mode range.
4 V- power_in Negative supply pin (or ground in single-supply operation). Total V+ to V- range: +2.7 V to +5.5 V (absolute max 7.0 V). Place a 0.1 µF decoupling capacitor close to the pin.
5 +IN B input Non-inverting input of amplifier B. High-impedance CMOS input; input bias current typ. 50 pA; rail-to-rail common-mode range.
6 -IN B input Inverting input of amplifier B. High-impedance CMOS input; input bias current typ. 50 pA; common-mode range extends 0.1 V beyond each supply rail.
7 OUT B output Output of amplifier B. Rail-to-rail CMOS output, short-circuit current typ. 50 mA, slew rate 2.7 V/µs, gain-bandwidth product 4.5 MHz.
8 V+ power_in Positive supply pin. Total V+ to V- range: +2.7 V to +5.5 V (absolute max 7.0 V). Place a 0.1 µF decoupling capacitor close to the pin.

CAD (KiCad official)

  • Symbol: RS8552XK
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: rs8552xk-etched.step / rs8552xk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs8552xk.step / rs8552xk.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs8552xk.step 122 KB You want the bare part, or you mark your own boards.
rs8552xk-etched.step 2.1 MB You want the part with RS8552XK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 502 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 03823b61f9fd241f, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
