TL081HIDR 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	NC	unconnected	Do not connect. Leave floating.
2	IN-	input	Inverting input of the op-amp. High-impedance JFET input; common-mode input range includes VCC+.
3	IN+	input	Non-inverting input of the op-amp. High-impedance JFET input; common-mode input range includes VCC+.
4	VCC-	power_in	Negative supply rail. For split-supply operation connect to negative rail (down to -20V); for single-supply operation connect to GND. Total supply range 4.5V to 40V.
5	NC	unconnected	Do not connect. Leave floating.
6	OUT	output	Op-amp output. Short-circuit protected. Rail-limited within the specified output swing.
7	VCC+	power_in	Positive supply rail. Up to +20V for split-supply operation or up to 40V single-supply relative to VCC-.
8	NC	unconnected	Do not connect. Leave floating. Note: on the TL081C PS variant this pin position is NC; the older TL081 has OFFSET N1/N2 on pins 1 and 5, but the TL081H removes offset trim.

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

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`tl081hidr.step`	122 KB	You want the bare part, or you mark your own boards.
`tl081hidr-etched.step`	1.8 MB	You want the part with `TL081HIDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 450 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.
