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.

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.
