ada4505-1arjz.lbr rebuild the library on adom-lbr 2.32.0. The published copy was built by 2.18.0, which imported every KiCad roundrect and oval pad as a SQUARE EAGLE smd; this carries the real pad shape across (0 -> 5 rounded pads) and stops dropping geometry drawn on KiCad User.N layers. Attributes, connects, pads and the pin-1 marker are gated against decreasing and are unchanged. · Ray 1mo ago

ADA4505-1ARJZ

UMW · Operational Amplifier · SOT-23-5

ADA4505-1ARJZ from UMW, in a SOT-23-5. 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 OUT output Amplifier output. Rail-to-rail; short-circuit current typ ±3.8 mA at 1.8 V supply and ±40 mA at 5 V supply; short-circuit to GND rated indefinite.
2 V- power_in Negative supply rail. Connect to GND for single-supply 1.8 V to 5 V operation, or to -0.9 V to -2.5 V for dual-supply operation. Total supply (V+ to V-) must not exceed 5.5 V absolute maximum.
3 +IN input Non-inverting input. Rail-to-rail common-mode range (0 V to V+). Typ input bias current 0.5 pA; input resistance ~220 GΩ; common-mode input capacitance ~4.7 pF. Internal clamp diodes to supply rails - limit input current to ≤10 mA when signal exceeds a rail by 0.1 V.
4 -IN input Inverting input. Rail-to-rail common-mode range (0 V to V+). Typ input bias current 0.5 pA; differential input capacitance ~2.5 pF. Internal clamp diodes to supply rails - limit input current to ≤10 mA when signal exceeds a rail by 0.1 V.
5 V+ power_in Positive supply rail. 1.8 V to 5 V (single-supply) or +0.9 V to +2.5 V (dual-supply). Absolute maximum supply voltage 5.5 V. Typical supply current 10 µA (max 11.5 µA at 1.8 V, 10.5 µA at 5 V).

CAD (KiCad official)

  • Symbol: ADA4505-1ARJZ
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ada4505-1arjz-etched.step / ada4505-1arjz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ada4505-1arjz.step / ada4505-1arjz.glb are the bare package body.

File Size Use it when
ada4505-1arjz.step 85 KB You want the bare part, or you mark your own boards.
ada4505-1arjz-etched.step 2.0 MB You want the part with ADA4505-1ARJZ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 514 faces against 102 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.
