LM258ADT

STMicroelectronics · Operational Amplifier · SO-8

LM258ADT from STMicroelectronics, in a SO-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. Can swing from 0 V up to (Vcc+ - 1.5 V); short-circuit protected with typical short-circuit output current ~40 mA when Vcc > 15 V.
2 In1- input Inverting input of op-amp channel 1. Input bias current typically 20 nA; input voltage range -0.3 V to 32 V; differential input voltage rating ±32 V.
3 In1+ input Non-inverting input of op-amp channel 1. Common-mode voltage range includes the negative rail (Vcc-/GND) up to Vcc+ - 1.5 V.
4 Vcc- power_in Negative supply / ground pin. In single-supply operation tie to GND; in dual-supply operation connect to the negative rail. Total supply span (Vcc+ to Vcc-) up to 32 V (or ±16 V).
5 In2+ input Non-inverting input of op-amp channel 2. Common-mode voltage range includes the negative rail (Vcc-/GND) up to Vcc+ - 1.5 V.
6 In2- input Inverting input of op-amp channel 2. Input bias current typically 20 nA; input offset voltage typically 2 mV.
7 Out2 output Output of op-amp channel 2. Rail-to-rail-lower output swing (0 V to Vcc+ - 1.5 V); short-circuit protected.
8 Vcc+ power_in Positive supply pin. Operates from 3 V up to 32 V single-supply (or ±16 V dual-supply). Very low quiescent current per channel, essentially independent of supply voltage.

CAD (KiCad official)

  • Symbol: LM258ADT
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SO-8 (KiCad packages3D, STEP)
  • 3D model files: lm258adt-etched.step / lm258adt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm258adt.step / lm258adt.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
lm258adt.step 122 KB You want the bare part, or you mark your own boards.
lm258adt-etched.step 1.6 MB You want the part with LM258ADT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 413 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.
