TPA1882-SR from 3PEAK, 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 | OUTA | output | Channel A op-amp output. Rail-to-rail output stage capable of swinging close to both supply rails. |
| 2 | -INA | input | Channel A inverting input. High-impedance input to the internal op-amp. |
| 3 | +INA | input | Channel A non-inverting input. High-impedance input; common-mode range extends to V-. |
| 4 | -VS | power_in | Negative power supply. Connect to ground for single-supply operation (4.5 V to 40 V VS) or to -2.25 V to -20 V for dual-supply operation. |
| 5 | +INB | input | Channel B non-inverting input. High-impedance input; common-mode range extends to V-. |
| 6 | -INB | input | Channel B inverting input. High-impedance input to the internal op-amp. |
| 7 | OUTB | output | Channel B op-amp output. Rail-to-rail output stage capable of swinging close to both supply rails. |
| 8 | +VS | power_in | Positive power supply. Operating range 4.5 V to 40 V (single supply) or +2.25 V to +20 V (dual supply). Absolute maximum 42 V. |

Two STEP files. Same geometry, different body top:

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 540 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.
