COS128C

COSINE · Instrumentation Amplifiers · SOP-8

COS128C 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 RG passive Gain setting pin. For gains greater than 1, place a gain resistor between pin 1 and pin 8.
2 VIN- power_in Negative input of the instrumentation amplifier.
3 VIN+ power_in Positive input of the instrumentation amplifier.
4 -VS power_in Negative supply; the operating voltage range is ±2.25V to ±18V (dual supply) per the recommended operating conditions.
5 REF input Reference input. This pin must be driven by low impedance or connected to ground.
6 VOUT output Output of the instrumentation amplifier.
7 +VS power_in Positive supply; the operating voltage range is ±2.25V to ±18V (dual supply) per the recommended operating conditions.
8 RG passive Gain setting pin. For gains greater than 1, place a gain resistor between pin 8 and pin 1.

CAD (KiCad official)

  • Symbol: COS128C
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cos128c-etched.step / cos128c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos128c.step / cos128c.glb are the bare package body.
