LM258 from IDCHIP, 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	1OUT	output	Output of op-amp channel 1. Can source ~40 mA and sink ~15 mA at VCC=15V.
2	1IN-	input	Inverting input of op-amp channel 1. Input bias current typ ±45 nA, max ±150 nA at VCM=0V.
3	1IN+	input	Non-inverting input of op-amp channel 1. Common-mode input voltage range 0 V to VCC-1.5 V.
4	GND	power_in	Ground / negative supply (VEE). Connect to 0 V for single-supply operation or to negative rail for dual-supply operation (down to -16 V).
5	2IN+	input	Non-inverting input of op-amp channel 2. Common-mode input voltage range 0 V to VCC-1.5 V.
6	2IN-	input	Inverting input of op-amp channel 2. Input bias current typ ±45 nA, max ±150 nA at VCM=0V.
7	2OUT	output	Output of op-amp channel 2. Can source ~40 mA and sink ~15 mA at VCC=15V.
8	VCC	power_in	Positive supply voltage. Absolute max 32 V (single supply) or ±16 V (split supply). Typical quiescent supply current 0.5 mA at VCC=5V, 1 mA at VCC=30V.

3D model: SOIC-8 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lm258.step`	122 KB	You want the bare part, or you mark your own boards.
`lm258-etched.step`	1.4 MB	You want the part with `LM258` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 336 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.
