op07cdr.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

OP07CDR

Texas Instruments · Precision OpAmps · SOIC-8

OP07CDR 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 OFFSET N1 input Offset null pin 1. Connect one end of an external 20 kΩ potentiometer here; the wiper goes to VCC+ to trim the input offset voltage.
2 IN- input Inverting input of the op-amp. Common-mode input voltage range ±13 V typ at VCC±=±15 V; input bias current ±1.8 nA typ.
3 IN+ input Non-inverting input of the op-amp. Common-mode input voltage range ±13 V typ at VCC±=±15 V; input bias current ±1.8 nA typ.
4 VCC- power_in Negative supply rail. Operating range -3 V to -18 V (referenced to VCC+ midpoint); absolute maximum -22 V.
5 NC unconnected No internal connection. Leave floating or tie to any convenient net.
6 OUT output Op-amp output. Peak output voltage ±13 V typ into RL ≥ 10 kΩ; output may be shorted to ground or either supply indefinitely.
7 VCC+ power_in Positive supply rail. Operating range +3 V to +18 V; absolute maximum +22 V. Also serves as the reference for the offset-null potentiometer wiper.
8 OFFSET N2 input Offset null pin 2. Connect the other end of the external 20 kΩ potentiometer here; potentiometer wiper returns to VCC+ for offset-voltage trimming. Adjustment range ±4 mV.

CAD (KiCad official)

  • Symbol: OP07CDR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: op07cdr-etched.step / op07cdr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); op07cdr.step / op07cdr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
op07cdr.step 122 KB You want the bare part, or you mark your own boards.
op07cdr-etched.step 1.6 MB You want the part with OP07CDR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 396 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.

Provenance

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

  • Datasheet: Texas Instruments datasheet (15 pp, sha256 c68e9ffdd5c60c1c, retrieved 2026-08-17, tier: manufacturer)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
