AS324AMTR-E1 from Diodes Incorporated, in a SOIC-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	OUTPUT1	output	Op-amp 1 output. Class-AB output stage with 0V to (Vcc-1.5V) swing; typical short-circuit current 40mA, source current 20mA typ, sink current 10mA typ at Vcc=15V.
2	INPUT1-	input	Op-amp 1 inverting input. Input bias current 20nA typ (100nA max); input voltage range -0.3V to +40V; common-mode range 0V to (Vcc-1.5V).
3	INPUT1+	input	Op-amp 1 non-inverting input. Input bias current 20nA typ; input common-mode range includes ground.
4	VCC	power_in	Positive supply voltage. Single-supply range 3V to 36V (absolute max 40V); dual-supply operation ±1.5V to ±18V also supported. Typical supply current 0.5mA (0.7mA typ at Vcc=5V, 1.0mA typ at Vcc=30V).
5	INPUT2+	input	Op-amp 2 non-inverting input. Same characteristics as INPUT1+.
6	INPUT2-	input	Op-amp 2 inverting input. Same characteristics as INPUT1-.
7	OUTPUT2	output	Op-amp 2 output. Same characteristics as OUTPUT1.
8	OUTPUT3	output	Op-amp 3 output. Same characteristics as OUTPUT1.
9	INPUT3-	input	Op-amp 3 inverting input. Same characteristics as INPUT1-.
10	INPUT3+	input	Op-amp 3 non-inverting input. Same characteristics as INPUT1+.
11	GND	power_in	Ground / negative supply return. For split-supply operation this pin becomes V- (negative rail).
12	INPUT4+	input	Op-amp 4 non-inverting input. Same characteristics as INPUT1+.
13	INPUT4-	input	Op-amp 4 inverting input. Same characteristics as INPUT1-.
14	OUTPUT4	output	Op-amp 4 output. Same characteristics as OUTPUT1.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`as324amtr-e1.step`	195 KB	You want the bare part, or you mark your own boards.
`as324amtr-e1-etched.step`	2.4 MB	You want the part with `AS324AMTR-E1` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 619 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.
