TP2261-TR

3PEAK · Operational Amplifier · SOT-23-5

TP2261-TR from 3PEAK, 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 Amplifier output. Rail-to-rail output stage; can drive loads referenced to Vs/2 (10kΩ typical test load).
2 -Vs power_in Negative supply rail. In single-supply operation connect to GND; in split-supply operation connect to V-. Supply range 3V to 36V total ((+Vs) − (−Vs)).
3 +IN input Non-inverting amplifier input. Input voltage range extends to -Vs (rail); input current must be limited to <10mA if driven beyond the supply.
4 -IN input Inverting amplifier input. Input voltage range extends to -Vs (rail); input current must be limited to <10mA if driven beyond the supply.
5 +Vs power_in Positive supply rail. Total supply (+Vs)−(−Vs) from 3V to 36V (40V abs max). Bypass locally with 0.1µF ceramic to -Vs.

Two STEP files. Same geometry, different body top:

File Size Use it when
tp2261-tr.step 85 KB You want the bare part, or you mark your own boards.
tp2261-tr-etched.step 1.5 MB You want the part with TP2261-TR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 382 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

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

  • Datasheet: 3PEAK datasheet (18 pp, sha256 2e32a162c52901fa, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
