LM258DR2G from onsemi, 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	OUTA	output	Output of amplifier A. Push-pull class-AB output; output-high limit typ 3.5 V at V_CC=5 V, R_L=2 kΩ; short-circuit current typ 40 mA.
2	INA-	input	Inverting input of amplifier A. Input bias current typ -45 nA; common-mode range 0 V to V_CC-1.7 V; V_IDR up to ±32 V without damage.
3	INA+	input	Non-inverting input of amplifier A. Input bias current typ -45 nA; common-mode range includes V_EE (ground).
4	VEE/GND	power_in	Negative supply / ground. Ground in single-supply operation; connect to negative rail (-1.5 V to -16 V) in split-supply operation.
5	INB+	input	Non-inverting input of amplifier B. Input bias current typ -45 nA; common-mode range includes V_EE (ground).
6	INB-	input	Inverting input of amplifier B. Input bias current typ -45 nA; V_IDR up to ±32 V without damage.
7	OUTB	output	Output of amplifier B. Push-pull class-AB output; short-circuit protected; typical source/sink 40/20 mA.
8	VCC	power_in	Positive supply. 3.0 V to 32 V single-supply, or +1.5 V to +16 V split-supply. Quiescent current typ 0.7 mA at V_CC=5 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm258dr2g.step`	122 KB	You want the bare part, or you mark your own boards.
`lm258dr2g-etched.step`	2.1 MB	You want the part with `LM258DR2G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 510 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.
