opa338na.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

OPA338NA

UMW · Operational Amplifier · SOT-23-5

OPA338NA 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	Op-amp output. Rail-to-rail output stage capable of driving loads to within millivolts of the supply rails.
2	V-	power_in	Negative supply rail (or GND for single-supply operation). Supply range typically +2.7 V to +5.5 V total (V+ to V-).
3	+In	input	Non-inverting input. High-impedance CMOS input with rail-to-rail input common-mode range.
4	-In	input	Inverting input. High-impedance CMOS input with rail-to-rail input common-mode range.
5	V+	power_in	Positive supply rail. Supply range typically +2.7 V to +5.5 V total (V+ to V-).

OPA338NA

CAD (KiCad official)

Symbol: OPA338NA
Footprint: Package_TO_SOT_SMD:SOT-23-5
3D model: SOT-23-5 (KiCad packages3D, STEP)
3D model files: opa338na-etched.step / opa338na-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa338na.step / opa338na.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`opa338na.step`	85 KB	You want the bare part, or you mark your own boards.
`opa338na-etched.step`	1.8 MB	You want the part with `OPA338NA` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 423 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.

Provenance

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

Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
