LMV324IDR 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 output stage swings within tens of mV of the supply rails under light load.
2	IN-A	input	Inverting input of op-amp channel A. High-impedance CMOS input.
3	IN+A	input	Non-inverting input of op-amp channel A. Common-mode input range extends from V- to (V+) - 1 V.
4	V+	power_in	Positive supply rail. Operates from 2.7 V to 5.5 V single supply (or ±1.35 V to ±2.75 V dual supply).
5	IN+B	input	Non-inverting input of op-amp channel B. High-impedance CMOS input.
6	IN-B	input	Inverting input of op-amp channel B. High-impedance CMOS input.
7	OUTB	output	Output of op-amp channel B. Rail-to-rail output stage.
8	OUTC	output	Output of op-amp channel C. Rail-to-rail output stage.
9	IN-C	input	Inverting input of op-amp channel C. High-impedance CMOS input.
10	IN+C	input	Non-inverting input of op-amp channel C. High-impedance CMOS input.
11	V-	power_in	Negative supply rail / ground. Tie to GND for single-supply operation.
12	IN+D	input	Non-inverting input of op-amp channel D. High-impedance CMOS input.
13	IN-D	input	Inverting input of op-amp channel D. High-impedance CMOS input.
14	OUTD	output	Output of op-amp channel D. Rail-to-rail output stage.

CAD (KiCad official)

Symbol: LMV324IDR
Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
3D model: SOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`lmv324idr.step`	195 KB	You want the bare part, or you mark your own boards.
`lmv324idr-etched.step`	2.0 MB	You want the part with `LMV324IDR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 517 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.
