rs358axk.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 8 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

RS358AXk

Jiangsu RUNIC Tech · Operational Amplifier · SOIC-8

RS358AXk 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, capable of sourcing up to ~130mA. Swings within 8mV of rail with RL=10kΩ and 25mV with RL=2kΩ.
2 -INA input Inverting input of amplifier A. Rail-to-rail input, common-mode voltage range -0.1V to +5.6V with Vs=5.5V. Ultra-low input bias current (~10pA typical).
3 +INA input Non-inverting input of amplifier A. Rail-to-rail input, common-mode voltage range -0.1V to +5.6V with Vs=5.5V. Ultra-low input bias current (~10pA typical).
4 V- power_in Negative supply pin (or ground for single-supply operation). Total supply range V+ to V- is 2.5V to 5.5V. Absolute maximum V+ to V- is 7.0V.
5 +INB input Non-inverting input of amplifier B. Rail-to-rail input, common-mode voltage range -0.1V to +5.6V with Vs=5.5V. Ultra-low input bias current (~10pA typical).
6 -INB input Inverting input of amplifier B. Rail-to-rail input, common-mode voltage range -0.1V to +5.6V with Vs=5.5V. Ultra-low input bias current (~10pA typical).
7 OUTB output Output of amplifier B. Rail-to-rail output, capable of sourcing up to ~130mA. Swings within 8mV of rail with RL=10kΩ and 25mV with RL=2kΩ.
8 V+ power_in Positive supply pin. Operating supply range 2.5V to 5.5V referenced to V-. Absolute maximum V+ to V- is 7.0V. Bypass with 0.1uF close to the pin.

Ordering variants

Same part, different packaging or reel option.

  • RS358AXM
  • RS358AXQ

CAD (KiCad official)

  • Symbol: RS358AXk
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: rs358axk-etched.step / rs358axk-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); rs358axk.step / rs358axk.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
rs358axk.step 122 KB You want the bare part, or you mark your own boards.
rs358axk-etched.step 2.0 MB You want the part with RS358AXk already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 497 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.
