LM224DR from UMW, in a SOP-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 | 1OUT | output | Amplifier 1 output. |
| 2 | 1IN- | input | Amplifier 1 inverting (negative) input. |
| 3 | 1IN+ | input | Amplifier 1 non-inverting (positive) input. |
| 4 | VCC | power_in | Positive supply. Single supply 3 V to 32 V (26 V for LM2902), or +Vs for split supply ±1.5 V to ±16 V. Typical ICC = 0.8 mA. |
| 5 | 2IN+ | input | Amplifier 2 non-inverting (positive) input. |
| 6 | 2IN- | input | Amplifier 2 inverting (negative) input. |
| 7 | 2OUT | output | Amplifier 2 output. |
| 8 | 3OUT | output | Amplifier 3 output. |
| 9 | 3IN- | input | Amplifier 3 inverting (negative) input. |
| 10 | 3IN+ | input | Amplifier 3 non-inverting (positive) input. |
| 11 | GND | power_in | Ground / negative supply. Tie to 0 V for single-supply operation or to -Vs for split supply. |
| 12 | 4IN+ | input | Amplifier 4 non-inverting (positive) input. |
| 13 | 4IN- | input | Amplifier 4 inverting (negative) input. |
| 14 | 4OUT | output | Amplifier 4 output. |

3D model downloads
Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
lm224dr.step |
195 KB | You want the bare part, or you mark your own boards. |
lm224dr-etched.step |
1.8 MB | You want the part with LM224DR already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 457 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
