LMC6081AIMX 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	No internal connection. Leave floating or tie to ground; do not use as a tie point.
2	IN-	input	Inverting input of the op-amp. High-impedance CMOS input; input bias current typically 10 fA. Absolute max input current ±10 mA; voltage must remain within (V-) - 0.3 V to (V+) + 0.3 V.
3	IN+	input	Non-inverting input of the op-amp. High-impedance CMOS input; input common-mode range includes V-. Absolute max input current ±10 mA; voltage must remain within (V-) - 0.3 V to (V+) + 0.3 V.
4	V-	power_in	Negative supply rail (or ground for single-supply operation). Supply range: V+ - V- ≤ 16 V absolute max, 4.5 V to 15.5 V operating. Typically tied to GND in single-supply designs.
5	NC	unconnected	No internal connection. Leave floating or tie to ground; do not use as a tie point.
6	OUT	output	Op-amp output. Rail-to-rail output swings to within 20 mV of the supply rails with a 100 kΩ load. Sourcing/sinking capability typically 22/21 mA at V+ = 5 V and 30/34 mA at V+ = 15 V. Do not connect to V+ when V+ > 13 V.
7	V+	power_in	Positive supply rail. Operating range 4.5 V to 15.5 V (single supply) or ±2.25 V to ±7.75 V (split). Typical supply current 450 µA at V+ = 5 V, 550 µA at V+ = 15 V. Bypass with 0.1 µF ceramic to V-.
8	NC	unconnected	No internal connection. Leave floating or tie to ground; do not use as a tie point.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmc6081aimx.step`	122 KB	You want the bare part, or you mark your own boards.
`lmc6081aimx-etched.step`	2.1 MB	You want the part with `LMC6081AIMX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 526 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.
