lm258m.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

LM258M

HGSEMI · Operational Amplifier · SOP-8

LM258M from HGSEMI, 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 1OUT output Output of op-amp channel 1. Short-circuit protected; typical short-circuit current ±24 mA at VCC=5V, VEE=-5V.
2 1IN- input Inverting input of op-amp channel 1. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V.
3 1IN+ input Non-inverting input of op-amp channel 1. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V.
4 VEE power_in Negative supply / ground pin. Tie to GND for single-supply operation (VCC 3V to 36V) or to negative rail for split-supply operation (up to ±18V).
5 2IN+ input Non-inverting input of op-amp channel 2. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V.
6 2IN- input Inverting input of op-amp channel 2. Input bias current typically 50 nA, common-mode range VEE to VCC-1.5V.
7 2OUT output Output of op-amp channel 2. Short-circuit protected; typical short-circuit current ±24 mA at VCC=5V, VEE=-5V.
8 VCC power_in Positive supply pin. Single-supply range 3V to 36V, dual-supply up to ±18V. Typical quiescent current 0.5 mA at VCC=5V, no load.

CAD (KiCad official)

  • Symbol: LM258M
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: lm258m-etched.step / lm258m-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm258m.step / lm258m.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm258m.step 122 KB You want the bare part, or you mark your own boards.
lm258m-etched.step 1.5 MB You want the part with LM258M already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 365 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.
