COS8091SOT

COSINE · Operational Amplifier · SOT23-5

COS8091SOT from COSINE, in a SOT23-5. 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. Output voltage swing extends to within millivolts of each supply rail (10 mV at RL=10 kΩ, 25 mV at RL=2 kΩ, 200 mV at RL=150 Ω).
2 -Vs power_in Negative power supply or ground. For single-supply operation tie to GND; for dual-supply operation bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible.
3 +IN input Non-inverting input of the amplifier. Common-mode voltage range is -Vs to +Vs (rail-to-rail); absolute input pin voltage range is -Vs -0.3 V to +Vs +0.3 V.
4 -IN input Inverting input of the amplifier. Voltage range at this pin is -Vs -0.3 V to +Vs +0.3 V; input bias current is typically ±3 pA.
5 +Vs power_in Positive power supply, 2.5 V to 5.5 V single-supply (or ±1.25 V to ±2.25 V dual-supply). Bypass with a 0.1 µF ceramic capacitor placed as close to the pin as possible.

CAD (KiCad official)

  • Symbol: COS8091SOT
  • Footprint: Package_TO_SOT_SMD:SOT-23-5
  • 3D model: SOT23-5 (KiCad packages3D, STEP)
  • 3D model files: cos8091sot-etched.step / cos8091sot-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos8091sot.step / cos8091sot.glb are the bare package body.

Provenance

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

  • Datasheet: COSINE datasheet (10 pp, sha256 b0fffdb283775e7b, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
