LMV324-SR from Gainsil, 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 amplifier A. Rail-to-rail output; swings within ~5mV of the supply rails into a 100kΩ load and can source/sink up to ~60mA (short-circuit).
2	INA-	input	Inverting input of amplifier A. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
3	INA+	input	Non-inverting input of amplifier A. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
4	VDD	power_in	Positive supply. Operating range 2.1V to 5.5V single-supply (or ±1.05V to ±2.75V dual-supply). Bypass with a 0.1µF ceramic capacitor to VSS close to the pin. Absolute max VDD−VSS = 7.5V.
5	INB+	input	Non-inverting input of amplifier B. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
6	INB-	input	Inverting input of amplifier B. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
7	OUTB	output	Output of amplifier B. Rail-to-rail output; swings within ~5mV of the supply rails into a 100kΩ load and can source/sink up to ~60mA (short-circuit).
8	OUTC	output	Output of amplifier C. Rail-to-rail output; swings within ~5mV of the supply rails into a 100kΩ load and can source/sink up to ~60mA (short-circuit).
9	INC-	input	Inverting input of amplifier C. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
10	INC+	input	Non-inverting input of amplifier C. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
11	VSS	power_in	Negative supply / ground. Tie to 0V in single-supply operation, or to the negative rail in dual-supply operation. Bypass with a 0.1µF ceramic capacitor.
12	IND+	input	Non-inverting input of amplifier D. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
13	IND-	input	Inverting input of amplifier D. High-impedance CMOS input, typical bias current 1pA. Common-mode range extends from VSS−0.1V to VDD+0.1V.
14	OUTD	output	Output of amplifier D. Rail-to-rail output; swings within ~5mV of the supply rails into a 100kΩ load and can source/sink up to ~60mA (short-circuit).

CAD (KiCad official)

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
`lmv324-sr.step`	195 KB	You want the bare part, or you mark your own boards.
`lmv324-sr-etched.step`	2.1 MB	You want the part with `LMV324-SR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 528 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.
