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. |
