lm258dr.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

LM258DR

Texas Instruments · Operational Amplifier · SOIC-8

LM258DR from Texas Instruments, 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 OUT1 output Output of op amp 1. Class-AB output stage swings from V- rail to within ~1.5 V of V+; short-circuit current ~40 mA typical.
2 IN1- input Inverting (negative) input of op amp 1. High input impedance (10 MΩ differential typical); input bias current ~-10 nA typical, -35 nA max (B/BA versions).
3 IN1+ input Non-inverting (positive) input of op amp 1. Common-mode input range extends from V- (ground in single-supply operation) up to V+ - 1.5 V.
4 V- power_in Negative (lowest) supply, or ground for single-supply operation. Total supply (V+ - V-) may range 3 V to 32 V (LM258/LM258A); absolute max 32 V.
5 IN2+ input Non-inverting (positive) input of op amp 2. Common-mode input range extends from V- (ground in single-supply operation) up to V+ - 1.5 V.
6 IN2- input Inverting (negative) input of op amp 2. High input impedance (10 MΩ differential typical); input bias current ~-10 nA typical (B/BA versions).
7 OUT2 output Output of op amp 2. Class-AB output stage swings from V- rail to within ~1.5 V of V+; short-circuit current ~40 mA typical.
8 V+ power_in Positive (highest) supply. Operating range 3 V to 32 V (LM258/LM258A) referenced to V-; quiescent current 300 µA per amplifier typical.

CAD (KiCad official)

  • Symbol: LM258DR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm258dr-etched.step / lm258dr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm258dr.step / lm258dr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm258dr.step 122 KB You want the bare part, or you mark your own boards.
lm258dr-etched.step 1.7 MB You want the part with LM258DR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 418 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.
