AS324MTR-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. Push-pull class-AB output stage capable of swinging from 0V to VCC−1.5V; source ~40mA typ, sink ~15mA typ; short-circuit current ~40mA typ at VCC=15V.
2	INPUT1-	input	Op-amp 1 inverting input. Input bias current 20nA typ (200nA max); input offset voltage 2mV typ; common-mode range 0V to VCC−1.5V.
3	INPUT1+	input	Op-amp 1 non-inverting input. Input common-mode range includes ground (0V) up to VCC−1.5V; inputs may go to +36V without damage independent of VCC magnitude.
4	VCC	power_in	Positive supply voltage. Operating range 3V to 36V single supply (or ±1.5V to ±18V split). Absolute maximum 40V. Total quiescent supply current 0.7mA typ at 5V, 1.0mA typ at 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	Device ground / negative supply. Single-supply operation ties this to 0V; split-supply operation ties this to the negative rail (down to −18V relative to VCC).
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.
