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

THS4521IDGKR

Texas Instruments · Differential OpAmps · MSOP-8

THS4521IDGKR from Texas Instruments, in a MSOP-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 VIN- input Inverting amplifier input. Analog signal input to the negative side of the fully differential amplifier.
2 VOCM input Output common-mode voltage control input. Sets the DC common-mode level of the differential outputs; leave floating to self-bias at mid-supply.
3 VS+ power_in Amplifier positive power-supply input. Total supply range VS+ to VS- of +2.5 V to +5.5 V (±1.25 V to ±2.75 V split supply). Bypass locally with 0.1 µF.
4 VOUT+ output Noninverting amplifier output. Rail-to-rail differential output; pairs with VOUT- to form the differential signal.
5 VOUT- output Inverting amplifier output. Rail-to-rail differential output complementary to VOUT+.
6 VS- power_in Amplifier negative power-supply input. Tie to ground for single-supply operation or to the negative rail for split-supply. Bypass locally with 0.1 µF.
7 PD input Active-low power-down. Logic low puts device into low-power mode (~20 µA typical); logic high or open enables normal operation.
8 VIN+ input Noninverting amplifier input. Analog signal input to the positive side of the fully differential amplifier.

CAD (KiCad official)

  • Symbol: THS4521IDGKR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: ths4521idgkr-etched.step / ths4521idgkr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ths4521idgkr.step / ths4521idgkr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
ths4521idgkr.step 123 KB You want the bare part, or you mark your own boards.
ths4521idgkr-etched.step 2.2 MB You want the part with THS4521IDGKR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 568 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.
