LM258ADR

Texas Instruments · Operational Amplifier · SOIC-8

LM258ADR 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 channel 1. Class-AB output stage able to sink and source current; short-circuit protected to V- (indefinite when Vs ≤ 15V at 25°C).
2 IN1- input Inverting (negative) input of op-amp channel 1. Common-mode range extends from V- to (V+ - 2V). Differential input voltage rating ±32V.
3 IN1+ input Non-inverting (positive) input of op-amp channel 1. Common-mode range extends from V- to (V+ - 2V), allowing direct sensing near ground in single-supply operation.
4 V- power_in Negative (lowest) supply rail. Tie to ground for single-supply operation. Supply voltage Vs = (V+) - (V-) rated 3V to 32V for LM258A.
5 IN2+ input Non-inverting (positive) input of op-amp channel 2. Common-mode range extends from V- to (V+ - 2V).
6 IN2- input Inverting (negative) input of op-amp channel 2. Differential input voltage rating ±32V.
7 OUT2 output Output of op-amp channel 2. Class-AB output; short-circuit protected to V-.
8 V+ power_in Positive (highest) supply rail. Supply voltage Vs = (V+) - (V-) rated 3V to 32V for LM258A (absolute maximum ±16V or 32V).

CAD (KiCad official)

  • Symbol: LM258ADR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: lm258adr-etched.step / lm258adr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm258adr.step / lm258adr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm258adr.step 122 KB You want the bare part, or you mark your own boards.
lm258adr-etched.step 1.8 MB You want the part with LM258ADR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 444 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: Texas Instruments datasheet (68 pp, sha256 ef646b009b0524a8, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
