lm124dr.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 -> 14 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

LM124DR

UMW · Operational Amplifier · SOP-14

LM124DR from UMW, in a SOP-14. 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 1. Push-pull output stage capable of driving loads to within ~1.5V of VCC (high-level) and near GND (low-level, ~5mV typical with RL≤10kΩ).
2 1IN- input Inverting (negative) input of op-amp 1. Input common-mode range includes ground (0 to VCC-1.5V typical). Input bias current typ -20 nA.
3 1IN+ input Non-inverting (positive) input of op-amp 1. Input common-mode range includes ground (0 to VCC-1.5V typical).
4 VCC power_in Positive supply voltage. Single-supply operation: 3V to 32V (26V max for LM2902). Dual-supply operation: ±1.5V to ±16V (±13V for LM2902). Typical quiescent current 0.8 mA.
5 2IN+ input Non-inverting (positive) input of op-amp 2. Input common-mode range includes ground.
6 2IN- input Inverting (negative) input of op-amp 2. Input common-mode range includes ground.
7 2OUT output Output of op-amp 2. Push-pull output stage; short-circuit duration to ground is unlimited (TA=25°C, VCC≤15V).
8 3OUT output Output of op-amp 3.
9 3IN- input Inverting (negative) input of op-amp 3.
10 3IN+ input Non-inverting (positive) input of op-amp 3.
11 GND power_in Ground / negative supply reference. All voltages (except differential and IOS test) are with respect to this network GND.
12 4IN+ input Non-inverting (positive) input of op-amp 4.
13 4IN- input Inverting (negative) input of op-amp 4.
14 4OUT output Output of op-amp 4.

CAD (KiCad official)

  • Symbol: LM124DR
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOP-14 (KiCad packages3D, STEP)
  • 3D model files: lm124dr-etched.step / lm124dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm124dr.step / lm124dr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm124dr.step 195 KB You want the bare part, or you mark your own boards.
lm124dr-etched.step 1.7 MB You want the part with LM124DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 437 faces against 237 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:
