jrc4558.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

JRC4558

MSKSEMI · Operational Amplifier · SOP-8

JRC4558 from MSKSEMI, 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 OUT1 output Amplifier A output. Op-amp output with short-circuit protection; can source/sink up to 5 mA at typical VOH=13.4 V (VCC+=15 V, Iout=-5 mA).
2 IN1- input Amplifier A inverting input. Typical input bias current 50 nA, offset current 10 nA. Common-mode range from VCC- to (VCC+ - 1.5 V).
3 IN1+ input Amplifier A non-inverting input. Typical input bias current 50 nA. Common-mode range from VCC- to (VCC+ - 1.5 V).
4 VCC- power_in Negative supply / ground. Connect to GND for single-supply operation (VCC+ = 3 V to 30 V) or to -15 V for dual-supply operation (±15 V). Absolute maximum single-supply 36 V, dual-supply ±18 V.
5 IN2+ input Amplifier B non-inverting input. Typical input bias current 50 nA. Common-mode range from VCC- to (VCC+ - 1.5 V).
6 IN2- input Amplifier B inverting input. Typical input bias current 50 nA, offset current 10 nA. Common-mode range from VCC- to (VCC+ - 1.5 V).
7 OUT2 output Amplifier B output. Op-amp output with short-circuit protection; can source/sink up to 5 mA at typical VOH=13.4 V (VCC+=15 V, Iout=-5 mA).
8 VCC+ power_in Positive supply. Single-supply range 3 V to 30 V (VCC- = GND) or dual-supply +15 V. Typical quiescent current 0.5 mA at VCC+=5 V, 0.8 mA at VCC+=30 V. Absolute maximum single-supply 36 V.

CAD (KiCad official)

  • Symbol: JRC4558
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: jrc4558-etched.step / jrc4558-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); jrc4558.step / jrc4558.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
jrc4558.step 122 KB You want the bare part, or you mark your own boards.
jrc4558-etched.step 1.8 MB You want the part with JRC4558 already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 446 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.
