## CAD (KiCad official)

- Symbol: `LM358AN`
- Footprint: `Package_DIP:DIP-8_W7.62mm`
- 3D model: PDIP-8 (KiCad packages3D, STEP)
- 3D model files: `lm358an-etched.step` / `lm358an-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `lm358an.step` / `lm358an.glb` are the bare package body.
