## CAD (KiCad official)

- Symbol: `LP324DR`
- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`
- 3D model: SOIC-14 (KiCad packages3D, STEP)
- 3D model files: `lp324dr-etched.step` / `lp324dr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lp324dr.step` / `lp324dr.glb` are the bare package body.
