ts321idbvr.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

TS321IDBVR

Texas Instruments · Operational Amplifier · SOT-23-5

TS321IDBVR from Texas Instruments, 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. Sources up to 40 mA typical (VCC=15 V), sinks up to 20 mA typical; short-circuit protected to ground.
2 VCC- power_in Negative supply pin. Tie to GND for single-supply operation (3 V to 30 V) or to the negative rail for dual-supply operation (±1.5 V to ±15 V). Absolute max VCC(single)=32 V, VCC(dual)=±16 V.
3 IN+ input Non-inverting op-amp input. Common-mode input range extends from VCC- to VCC+ - 1.5 V; typical input bias current 20 nA (out of the device).
4 IN- input Inverting op-amp input. Common-mode input range extends from VCC- to VCC+ - 1.5 V; differential input voltage abs-max ±32 V.
5 VCC+ power_in Positive supply pin. Recommended 3 V to 30 V single-supply (or up to ±15 V dual). Typical total supply current 500 µA at VCC=5 V, no load.

CAD (KiCad official)

  • Symbol: TS321IDBVR
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: ts321idbvr-etched.step / ts321idbvr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ts321idbvr.step / ts321idbvr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
ts321idbvr.step 85 KB You want the bare part, or you mark your own boards.
ts321idbvr-etched.step 1.9 MB You want the part with TS321IDBVR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 468 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
