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. |
