LM324N 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 | 1OUT | output | First operational amplifier output |
| 2 | 1IN- | input | First stage inverting input with high impedance 2MΩ parallel 0.1pF |
| 3 | 1IN+ | input | First stage non-inverting input with high impedance 2MΩ parallel 0.1pF, common mode voltage range V- to (V+)-1.5V |
| 4 | VCC+ | power_in | Positive supply voltage, operating range 3V to 30V for LM324 variants |
| 5 | 2IN+ | input | Second stage non-inverting input with high impedance 2MΩ parallel 0.1pF, common mode voltage range V- to (V+)-1.5V |
