opa2990idr.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

OPA2990IDR

Texas Instruments · Operational Amplifier · SOIC-8

OPA2990IDR from Texas Instruments, in a SOIC-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 OUT1 output Amplifier channel 1 output. Rail-to-rail output stage, capable of ±80 mA short-circuit current.
2 IN1- input Inverting input of amplifier channel 1. Rail-to-rail input; common-mode range extends beyond both supply rails.
3 IN1+ input Noninverting input of amplifier channel 1. Rail-to-rail input; common-mode range extends beyond both supply rails.
4 V- power_in Negative (lowest) power-supply pin. Total supply range 2.7 V to 40 V (single-supply) or ±1.35 V to ±20 V (dual-supply). Bypass to V+ with a 0.1 µF ceramic.
5 IN2+ input Noninverting input of amplifier channel 2. Rail-to-rail input; common-mode range extends beyond both supply rails.
6 IN2- input Inverting input of amplifier channel 2. Rail-to-rail input; common-mode range extends beyond both supply rails.
7 OUT2 output Amplifier channel 2 output. Rail-to-rail output stage, capable of ±80 mA short-circuit current.
8 V+ power_in Positive (highest) power-supply pin. Total supply range 2.7 V to 40 V (single-supply) or ±1.35 V to ±20 V (dual-supply). Bypass to V- with a 0.1 µF ceramic.

CAD (KiCad official)

  • Symbol: OPA2990IDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: opa2990idr-etched.step / opa2990idr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); opa2990idr.step / opa2990idr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
opa2990idr.step 122 KB You want the bare part, or you mark your own boards.
opa2990idr-etched.step 2.2 MB You want the part with OPA2990IDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 546 faces against 147 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.
