COSINA333MRA

COSINE · Instrumentation Amplifiers · MSOP-8

COSINA333MRA 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 RG passive Gain setting pin; for gains greater than 1, place a gain resistor between pins 1 and 8.
2 VIN- power_in Negative input.
3 VIN+ power_in Positive input.
4 -VS power_in Negative supply.
5 REF input Reference input; must be driven by low impedance or connected to ground.
6 VOUT output Output.
7 +VS power_in Positive supply.
8 RG passive Gain setting pin; for gains greater than 1, place a gain resistor between pins 1 and 8.

CAD (KiCad official)

  • Symbol: COSINA333MRA
  • Footprint: Package_SO:MSOP-8_3x3mm_P0.65mm
  • 3D model: MSOP-8 (KiCad packages3D, STEP)
  • 3D model files: cosina333mra-etched.step / cosina333mra-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cosina333mra.step / cosina333mra.glb are the bare package body.
