LM224DT

STMicroelectronics · Operational Amplifier · SOIC-14

LM224DT from STMicroelectronics, 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 Output 1 output Output of op-amp 1.
2 Inverting Input 1 input Inverting input (-) of op-amp 1. Vin -0.3 V to 32 V; input bias 20 nA typ.
3 Non-inverting Input 1 input Non-inverting input (+) of op-amp 1. Common-mode range includes ground (0 V to VCC-1.5 V).
4 VCC+ power_in Positive supply. Single supply +3 V to +30 V, or dual supply +1.5 V to +15 V. Absolute max ±16 V or 32 V total.
5 Non-inverting Input 2 input Non-inverting input (+) of op-amp 2.
6 Inverting Input 2 input Inverting input (-) of op-amp 2.
7 Output 2 output Output of op-amp 2. Short-circuit protected; typical short-circuit current ~40 mA.
8 Output 3 output Output of op-amp 3.
9 Inverting Input 3 input Inverting input (-) of op-amp 3.
10 Non-inverting Input 3 input Non-inverting input (+) of op-amp 3.
11 VCC- power_in Negative supply / ground. Tie to GND for single-supply operation, or to a negative rail (down to -15 V) for dual-supply operation.
12 Non-inverting Input 4 input Non-inverting input (+) of op-amp 4.
13 Inverting Input 4 input Inverting input (-) of op-amp 4.
14 Output 4 output Output of op-amp 4.

CAD (KiCad official)

  • Symbol: LM224DT
  • Footprint: Package_SO:SOIC-14_3.9x8.7mm_P1.27mm
  • 3D model: SOIC-14 (KiCad packages3D, STEP)
  • 3D model files: lm224dt-etched.step / lm224dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lm224dt.step / lm224dt.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
lm224dt.step 195 KB You want the bare part, or you mark your own boards.
lm224dt-etched.step 1.6 MB You want the part with LM224DT already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 426 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.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (19 pp, sha256 29f770052e84d04e, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
