ada4505-4aruz.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 -> 14 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

ADA4505-4ARUZ

UMW · Operational Amplifier · TSSOP-14

ADA4505-4ARUZ from UMW, in a TSSOP-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 OUT A output Amplifier A output. Rail-to-rail output; short-circuit limited to ±40 mA (5 V supply). Drives loads down to ~10 kΩ with output swing to within tens of mV of the rails.
2 -IN A input Inverting input of amplifier A. High-impedance input (~220 GΩ), 0.5 pA typical bias current. Input voltage range extends from V- to V+.
3 +IN A input Non-inverting input of amplifier A. Rail-to-rail input, high-impedance (~220 GΩ), 0.5 pA typical bias current.
4 V+ power_in Positive supply rail. Single-supply 1.8 V to 5 V (absolute maximum 5.5 V) or dual ±0.9 V to ±2.5 V. Common to all four amplifiers.
5 +IN B input Non-inverting input of amplifier B. Rail-to-rail input, high-impedance (~220 GΩ), 0.5 pA typical bias current.
6 -IN B input Inverting input of amplifier B. High-impedance input (~220 GΩ), 0.5 pA typical bias current.
7 OUT B output Amplifier B output. Rail-to-rail output; short-circuit limited to ±40 mA (5 V supply).
8 OUT C output Amplifier C output. Rail-to-rail output; short-circuit limited to ±40 mA (5 V supply).
9 -IN C input Inverting input of amplifier C. High-impedance input (~220 GΩ), 0.5 pA typical bias current.
10 +IN C input Non-inverting input of amplifier C. Rail-to-rail input, high-impedance (~220 GΩ), 0.5 pA typical bias current.
11 V- power_in Negative supply rail / ground for single-supply operation. Tie to GND for 1.8-5 V single-supply use, or to negative rail for ±0.9 V to ±2.5 V dual-supply operation.
12 +IN D input Non-inverting input of amplifier D. Rail-to-rail input, high-impedance (~220 GΩ), 0.5 pA typical bias current.
13 -IN D input Inverting input of amplifier D. High-impedance input (~220 GΩ), 0.5 pA typical bias current.
14 OUT D output Amplifier D output. Rail-to-rail output; short-circuit limited to ±40 mA (5 V supply).

  • 3D model files: ada4505-4aruz-etched.step / ada4505-4aruz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ada4505-4aruz.step / ada4505-4aruz.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ada4505-4aruz.step 194 KB You want the bare part, or you mark your own boards.
ada4505-4aruz-etched.step 2.6 MB You want the part with ADA4505-4ARUZ already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 663 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.
