TPA1882-SR

3PEAK · Operational Amplifier · SOIC-8

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:

File Size Use it when
tpa1882-sr.step 122 KB You want the bare part, or you mark your own boards.
tpa1882-sr-etched.step 2.2 MB You want the part with TPA1882-SR already on it.

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.

Provenance

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

  • Datasheet: 3PEAK datasheet (20 pp, sha256 a278ff47eef5b049, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
