COS358SR

COSINE · Operational Amplifier · SOIC-8

COS358SR from COSINE, 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 Output of amplifier A. Rail-to-rail output; swings to within ~10mV of each supply rail (1mV @ 100kΩ, 10mV @ 10kΩ, 40mV @ 2kΩ). Short-circuit current typ. 45mA source / 50mA sink.
2 -IN1 input Inverting (negative) input of amplifier A. Input voltage range from -Vs -0.3V to +Vs - 1V. Input terminals are diode-clamped to the supply rails; signals exceeding rails by >0.5V must be current-limited to 10mA.
3 +IN1 input Non-inverting (positive) input of amplifier A. Same voltage range as the inverting input (-Vs -0.3V to +Vs - 1V). Common-mode range with Vs=5.5V spans -0.1V to 4.5V; CMRR typ. 125dB.
4 -Vs power_in Negative supply / ground pin. For single-supply operation tie to GND; for dual-supply operation connect to negative rail (±1.05V to ±2.75V). Bypass with 0.1µF ceramic close to the pin if not tied directly to ground.
5 +IN2 input Non-inverting (positive) input of amplifier B. Same voltage-range and common-mode specifications as +IN1.
6 -IN2 input Inverting (negative) input of amplifier B. Input voltage range from -Vs -0.3V to +Vs - 1V; diode-clamped to supplies.
7 OUTB output Output of amplifier B. Rail-to-rail; same drive characteristics as OUTA.
8 +Vs power_in Positive supply pin. Operating range 2.1V to 5.5V (single supply) or ±1.05V to ±2.75V (dual). Bypass with a 0.1µF ceramic capacitor placed as close as possible to this pin (2.2µF tantalum optional for improved performance). Total quiescent current ~170µA (85µA per amplifier).

CAD (KiCad official)

  • Symbol: COS358SR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOIC-8 (KiCad packages3D, STEP)
  • 3D model files: cos358sr-etched.step / cos358sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos358sr.step / cos358sr.glb are the bare package body.

Two STEP files. Same geometry, different body top:

File Size Use it when
cos358sr.step 122 KB You want the bare part, or you mark your own boards.
cos358sr-etched.step 2.4 MB You want the part with COS358SR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 551 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.
