COSOP27SRB

COSINE · Precision Op Amps · SOP-8

COSOP27SRB from COSINE, in a SOP-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 per the pin diagram; the pin table also describes an optional VOS trim function where a nulling resistor (e.g. 20kΩ) goes between pins 1 and 8.
2 -IN input Inverting input of the amplifier, with a voltage range from -Vs to +Vs.
3 +IN input Non-inverting input of the amplifier, with the same voltage range as -IN.
4 -Vs power_in Negative power supply or ground; if not connected to ground, bypass it with a 0.1μF capacitor placed as close to the part as possible.
5 NC unconnected No connection.
6 OUT output Amplifier output, whose voltage range extends to within millivolts of each supply rail.
7 +Vs power_in Positive power supply, with a 0.1μF bypass capacitor placed as close to the part as possible between the supply pins or between the supply pins and ground.
8 NC unconnected No connection per the pin diagram; the pin table also describes an optional VOS trim function where a nulling resistor (e.g. 20kΩ) goes between pins 1 and 8.

CAD (KiCad official)

  • Symbol: COSOP27SRB
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cosop27srb-etched.step / cosop27srb-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cosop27srb.step / cosop27srb.glb are the bare package body.
