LF444CN

Texas Instruments · FET Input Amplifiers · DIP-14

LF444CN from Texas Instruments, in a DIP-14. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin	Name	Type	Function
1	OUT1	output	Output of amplifier 1; drives a 10 kΩ load to ±10V over the full temperature range.
2	IN1-	input	Inverting input of amplifier 1 (JFET input); must not exceed the negative supply.
3	IN1+	input	Non-inverting input of amplifier 1 (JFET input); must not exceed the negative supply.
4	V+	power_in	Positive supply; absolute maximum supply voltage is ±18V for the LF444, and the amplifiers operate with supplies down to ±3.0V.
5	IN2+	input	Non-inverting input of amplifier 2 (JFET input); must not exceed the negative supply.
6	IN2-	input	Inverting input of amplifier 2 (JFET input); must not exceed the negative supply.
7	OUT2	output	Output of amplifier 2; may be shorted to ground indefinitely, but not more than one output at once.
8	OUT3	output	Output of amplifier 3; may be shorted to ground indefinitely, but not more than one output at once.
9	IN3-	input	Inverting input of amplifier 3 (JFET input); must not exceed the negative supply.
10	IN3+	input	Non-inverting input of amplifier 3 (JFET input); must not exceed the negative supply.
11	V-	power_in	Negative supply; input voltages must not be allowed to exceed it, and the supply must never be reversed in polarity.
12	IN4+	input	Non-inverting input of amplifier 4 (JFET input); must not exceed the negative supply.
13	IN4-	input	Inverting input of amplifier 4 (JFET input); must not exceed the negative supply.
14	OUT4	output	Output of amplifier 4; may be shorted to ground indefinitely, but not more than one output at once.
