LMV611MF from UMW, in a SOT-23-5. 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	+IN	input	Noninverting analog input of the op-amp. Input common-mode range extends 200 mV beyond either supply rail.
2	V-	power_in	Negative supply input (VSS/GND). Single-supply operation ties this pin to ground; total supply range 1.8 V to 5 V referenced to V+.
3	-IN	input	Inverting analog input of the op-amp. Input common-mode range extends 200 mV beyond either supply rail.
4	OUTPUT	output	Rail-to-rail op-amp output. Swings within 30 mV of the rails driving a 2 kΩ load, or 80 mV driving 600 Ω, at 1.8 V supply.
5	V+	power_in	Positive supply input. Operating range 1.8 V to 5 V referenced to V-; quiescent current ~100 µA per channel.

3D model: SOT-23-5 (KiCad packages3D, STEP)

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv611mf.step`	85 KB	You want the bare part, or you mark your own boards.
`lmv611mf-etched.step`	1.1 MB	You want the part with `LMV611MF` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 305 faces against 102 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.
