COS8551TRC

COSINE · Precision OpAmps · SOT-23-5

COS8551TRC from COSINE, 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; voltage swing extends to within ~5 mV of each supply rail (RL=100 kΩ) or ~15 mV (RL=10 kΩ). Short-circuit current ±7 mA (typ).
2 -Vs power_in Negative supply / ground. If not tied to ground, bypass with 0.1 µF as close to the pin as possible. Total supply +Vs to -Vs must not exceed 6 V.
3 +IN input Non-inverting input. Common-mode range -Vs - 0.3 V to +Vs + 0.3 V (rail-to-rail input). Input bias current ±100 pA typ (±500 pA max).
4 -IN input Inverting input. Common-mode range -Vs - 0.3 V to +Vs + 0.3 V. Input bias current ±100 pA typ (±500 pA max).
5 +Vs power_in Positive supply, 1.8 V to 5.5 V. Bypass with a 0.1 µF capacitor placed as close to the pin as possible, between +Vs and -Vs (or +Vs and ground). Absolute maximum +Vs to -Vs is 6 V.

CAD (KiCad official)

  • Symbol: COS8551TRC
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT-23-5 (KiCad packages3D, STEP)
  • 3D model files: cos8551trc-etched.step / cos8551trc-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos8551trc.step / cos8551trc.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
cos8551trc.step 85 KB You want the bare part, or you mark your own boards.
cos8551trc-etched.step 2.2 MB You want the part with COS8551TRC already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 510 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.
