LF444CMX from Texas Instruments, 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	OUT1	output	Amplifier 1 output.
2	IN1-	input	Amplifier 1 inverting input (JFET gate, ~10^12 Ω, 50 pA max bias).
3	IN1+	input	Amplifier 1 non-inverting input (JFET gate, ~10^12 Ω, 50 pA max bias).
4	V+	power_in	Positive supply rail (VCC). Absolute max ±18 V (LF444) / ±22 V (LF444A). Typical operation ±15 V. Supply current ~0.6 mA (all four amps).
5	IN2+	input	Amplifier 2 non-inverting input.
6	IN2-	input	Amplifier 2 inverting input.
7	OUT2	output	Amplifier 2 output.
8	OUT3	output	Amplifier 3 output.
9	IN3+	input	Amplifier 3 non-inverting input.
10	IN3-	input	Amplifier 3 inverting input.
11	V-	power_in	Negative supply rail (VEE). Absolute max ±18 V (LF444) / ±22 V (LF444A). Tie to GND for single-supply operation.
12	IN4+	input	Amplifier 4 non-inverting input.
13	IN4-	input	Amplifier 4 inverting input.
14	OUT4	output	Amplifier 4 output.
