opa340ua.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 -> 8 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

OPA340UA

UMW · Operational Amplifier · SOP-8

OPA340UA from UMW, in a SOP-8. 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 NC unconnected No internal connection. Can be left floating.
2 -IN input Negative (inverting) input of the op-amp. Rail-to-rail input; common-mode range extends 500 mV below V- and 500 mV above V+.
3 +IN input Positive (noninverting) input of the op-amp. Rail-to-rail input; common-mode range extends 500 mV below V- and 500 mV above V+.
4 V- power_in Negative (lowest) power supply. Typically GND in single-supply configurations. Total supply range V+ to V- is 2.5 V to 5.5 V.
5 NC unconnected No internal connection. Can be left floating.
6 OUT output Op-amp output. Rail-to-rail output swings to within 1 mV of V+/V- with a 100-kΩ load.
7 V+ power_in Positive (highest) power supply. Single-supply operation from 2.5 V to 5.5 V (dual-supply ±1.25 V to ±2.75 V).
8 NC unconnected No internal connection. Can be left floating.

Provenance

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

  • Datasheet: UMW datasheet (18 pp, sha256 e75e687924f6aa75, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
