LM324N

Texas Instruments · Operational Amplifier · DIP-14

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
6 2IN- input Second stage inverting input with high impedance 2MΩ parallel 0.1pF
7 2OUT output Second operational amplifier output
8 3OUT output Third operational amplifier output
9 3IN- input Third stage inverting input with high impedance 2MΩ parallel 0.1pF
10 3IN+ input Third stage non-inverting input with high impedance 2MΩ parallel 0.1pF, common mode voltage range V- to (V+)-1.5V
11 VCC- power_in Negative supply voltage or ground for single-supply operation, reference point for all voltage measurements
12 4IN+ input Fourth stage non-inverting input with high impedance 2MΩ parallel 0.1pF, common mode voltage range V- to (V+)-1.5V
13 4IN- input Fourth stage inverting input with high impedance 2MΩ parallel 0.1pF
14 4OUT output Fourth operational amplifier output

CAD (KiCad official)

  • Symbol: LM324N
  • Footprint: Package_DIP:DIP-14_W7.62mm
  • 3D model: DIP-14 (KiCad packages3D, STEP)
  • 3D model files: lm324n-etched.step / lm324n-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm324n.step / lm324n.glb are the bare package body.
