COS722MR

COSINE · Operational Amplifier · MSOP-8

COS722MR 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 OUT1 output Amplifier A output. Rail-to-rail output; swing extends to within ~1 mV (RL=100kΩ), 8 mV (RL=10kΩ), or 40 mV (RL=2kΩ) of each supply rail. Short-circuit sourcing/sinking ~21/22 mA.
2 -IN1 input Amplifier A inverting input. Voltage range -Vs -0.3V to +Vs +0.3V. Input bias current ±2.5 pA typ; input terminals are diode-clamped to the supply rails (limit current to 10 mA if driven beyond rails).
3 +IN1 input Amplifier A non-inverting input. Same voltage range as -IN1 (-Vs -0.3V to +Vs +0.3V). Rail-to-rail common-mode input range.
4 -Vs power_in Negative power supply or ground. For single-supply operation tie to ground; for dual-supply operation (±1.25V to ±2.75V) bypass to ground with a 0.1µF ceramic cap placed close to the pin. Total supply span (+Vs to -Vs) is 6.0 V absolute maximum.
5 +IN2 input Amplifier B non-inverting input. Same voltage range as -IN (-Vs -0.3V to +Vs +0.3V). Rail-to-rail common-mode input range.
6 -IN2 input Amplifier B inverting input. Voltage range -Vs -0.3V to +Vs +0.3V. Input bias current ±2.5 pA typ; diode-clamped to rails.
7 OUT2 output Amplifier B output. Rail-to-rail output; swing extends to within a few mV of each supply rail. Short-circuit sourcing/sinking ~21/22 mA.
8 +Vs power_in Positive power supply, 2.5V to 5.5V (single-supply) or +1.25V to +2.75V (dual-supply). Absolute maximum +Vs to -Vs is 6.0 V. Bypass with a 0.1µF ceramic capacitor placed as close to the pin as possible; a 2.2µF tantalum may be added for improved performance. Quiescent current ~650 µA per amplifier.

Ordering variants

Same part, different packaging or reel option.

  • COS722MR
  • COS722SR

CAD (KiCad official)

  • Symbol: COS722MR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: cos722mr-etched.step / cos722mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos722mr.step / cos722mr.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
cos722mr.step 123 KB You want the bare part, or you mark your own boards.
cos722mr-etched.step 1.8 MB You want the part with COS722MR already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 451 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
