COS358MR

COSINE · Operational Amplifier · MSOP-8

COS358MR from COSINE, in a MSOP-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 Output of amplifier A. Rail-to-rail output that extends to within millivolts of each supply rail.
2 -INA input Inverting input of amplifier A. Voltage range from -Vs -0.3V to +Vs - 1V. Input terminals are diode-clamped to the power-supply rails.
3 +INA input Non-inverting input of amplifier A. Voltage range from -Vs -0.3V to +Vs - 1V.
4 -Vs power_in Negative power supply or ground. If not connected to ground, bypass with a 0.1µF capacitor as close to the part as possible. Supply range 2.1V to 5.5V total between +Vs and -Vs.
5 +INB input Non-inverting input of amplifier B. Voltage range from -Vs -0.3V to +Vs - 1V.
6 -INB input Inverting input of amplifier B. Voltage range from -Vs -0.3V to +Vs - 1V. Input terminals are diode-clamped to the power-supply rails.
7 OUTB output Output of amplifier B. Rail-to-rail output that extends to within millivolts of each supply rail.
8 +Vs power_in Positive power supply, 2.1V to 5.5V. Bypass with a 0.1µF ceramic capacitor placed as close to the pin as possible.

Ordering variants

Same part, different packaging or reel option.

  • COS358MR
  • COS358MRSR

CAD (KiCad official)

  • Symbol: COS358MR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: cos358mr-etched.step / cos358mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos358mr.step / cos358mr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
cos358mr.step 123 KB You want the bare part, or you mark your own boards.
cos358mr-etched.step 2.2 MB You want the part with COS358MR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 521 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: COSINE datasheet (10 pp, sha256 7499c4d7cd32eb92, 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).
