COSOP27SRC

COSINE · Precision Op Amps · SOP-8

COSOP27SRC 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, although the pin function table also mentions an optional VOS trim resistor (e.g. 20kΩ) between pins 1 and 8.
2 -IN input Inverting input of the amplifier, whose voltage range can go 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, to be bypassed with a 0.1µF capacitor placed as close to the part as possible.
8 NC unconnected No connection per the pin diagram, although the pin function table also mentions an optional VOS trim resistor (e.g. 20kΩ) between pins 1 and 8.

CAD (KiCad official)

  • Symbol: COSOP27SRC
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cosop27src-etched.step / cosop27src-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cosop27src.step / cosop27src.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: COSINE datasheet (8 pp, sha256 43c6ffa5d6a958ab, retrieved 2026-10-27, tier: lcsc)
  • Extractor: parts-factory 2.0.0 / extract_pins 0.3, primary claude-sonnet-5-5 (text+vision), consensus claude-opus-5-5 (agreed), guards: pin_guards 0.1: passed. Pins are checked against the footprint pad set and their cited datasheet pages before publish.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
