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).

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.
