COS1177MR

COSINE · Precision Op Amps · MSOP-8

COS1177MR from COSINE, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 NC unconnected No connection.
2 -IN input Inverting input of the amplifier; voltage range can go from -Vs to +Vs.
3 +IN input Non-inverting input of the amplifier; same voltage range as -IN (-Vs to +Vs).
4 -Vs power_in Negative power supply or ground; if not connected to ground, bypass with a 0.1µF capacitor placed as close to the part as possible.
5 NC unconnected No connection.
6 OUT output Amplifier output; the output voltage range extends to within millivolts of each supply rail.
7 +Vs power_in Positive power supply; place a 0.1µF bypass capacitor as close to the part as possible between the supply pins or between the supply pins and ground.
8 NC unconnected No connection.

CAD (KiCad official)

  • Symbol: COS1177MR
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: cos1177mr-etched.step / cos1177mr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos1177mr.step / cos1177mr.glb are the bare package body.
