LMV614MAX from UMW, in a SOP-14. 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 op-amp channel A. Rail-to-rail push-pull output; swings within 30 mV of the supply rails with a 2-kΩ load and within 80 mV with a 600-Ω load.
2	INA-	input	Inverting input of op-amp channel A. High-impedance CMOS input; common-mode range extends 200 mV beyond both supply rails.
3	INA+	input	Noninverting input of op-amp channel A. High-impedance CMOS input; common-mode range extends 200 mV beyond both supply rails.
4	V+	power_in	Positive supply input. Operating supply range 1.8 V to 5 V (single supply) or ±0.9 V to ±2.5 V (dual supply). Bypass to ground with a ceramic decoupling capacitor.
5	INB+	input	Noninverting input of op-amp channel B. High-impedance CMOS input; common-mode range extends 200 mV beyond both supply rails.
6	INB-	input	Inverting input of op-amp channel B. High-impedance CMOS input; common-mode range extends 200 mV beyond both supply rails.
7	OUTB	output	Output of op-amp channel B. Rail-to-rail push-pull output.
8	OUTC	output	Output of op-amp channel C. Rail-to-rail push-pull output.
9	INC-	input	Inverting input of op-amp channel C. High-impedance CMOS input.
10	INC+	input	Noninverting input of op-amp channel C. High-impedance CMOS input.
11	V-	power_in	Negative supply input. Tie to ground for single-supply operation, or to the negative rail for split-supply operation.
12	IND+	input	Noninverting input of op-amp channel D. High-impedance CMOS input.
13	IND-	input	Inverting input of op-amp channel D. High-impedance CMOS input.
14	OUTD	output	Output of op-amp channel D. Rail-to-rail push-pull output.

CAD (KiCad official)

3D model: SOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv614max.step`	195 KB	You want the bare part, or you mark your own boards.
`lmv614max-etched.step`	1.7 MB	You want the part with `LMV614MAX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 463 faces against 237 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.
