RS8412XK

Jiangsu RUNIC Tech · Operational Amplifier · SOP-8

RS8412XK from Jiangsu RUNIC Tech, in a SOP-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, channel A. Rail-to-rail output stage, short-circuit current ~70mA, drives capacitive loads up to 100pF.
2 -INA input Inverting input, channel A. Diode-clamped to supply rails; keep input current below ±10mA. Common-mode range extends from (V-)-0.1V to (V+)-2V.
3 +INA input Noninverting input, channel A. Diode-clamped to supply rails; keep input current below ±10mA. Common-mode range extends from (V-)-0.1V to (V+)-2V.
4 V- power_in Negative (lowest) power supply pin, or ground for single-supply operation. Total supply Vs=(V+)-(V-) may range from 3V to 36V (single) or ±1.5V to ±18V (dual).
5 +INB input Noninverting input, channel B. Diode-clamped to supply rails; keep input current below ±10mA. Common-mode range extends from (V-)-0.1V to (V+)-2V.
6 -INB input Inverting input, channel B. Diode-clamped to supply rails; keep input current below ±10mA. Common-mode range extends from (V-)-0.1V to (V+)-2V.
7 OUTB output Output, channel B. Rail-to-rail output stage, short-circuit current ~70mA, drives capacitive loads up to 100pF.
8 V+ power_in Positive (highest) power supply pin. Total supply Vs=(V+)-(V-) may range from 3V to 36V (single) or ±1.5V to ±18V (dual). PSRR typical 120dB.

Ordering variants

Same part, different packaging or reel option.

  • RS8412XK

CAD (KiCad official)

  • Symbol: RS8412XK
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: rs8412xk-etched.step / rs8412xk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs8412xk.step / rs8412xk.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs8412xk.step 122 KB You want the bare part, or you mark your own boards.
rs8412xk-etched.step 1.9 MB You want the part with RS8412XK already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 465 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:
