COS620ARZ

COSINE · Instrumentation OpAmps · SOP-8

COS620ARZ 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, a gain resistor is placed between pins 1 and 8, with gain G = 1 + 49.4 kΩ/RG.
2 VIN- power_in Negative input of the instrumentation amplifier, with common-mode input range of -Vs+1.9 V to +Vs-1.2 V.
3 VIN+ power_in Positive input of the instrumentation amplifier, with common-mode input range of -Vs+1.9 V to +Vs-1.2 V.
4 -VS power_in Negative supply; dual supplies from ±2.25 V to ±18 V, with the -Vs supply bypassed to ground by a separate 0.1 µF ceramic capacitor.
5 REF input Reference input that must be driven by a low-impedance source or connected to ground; a series resistance of 8 Ω degrades common-mode rejection to about 80 dB.
6 VOUT output Amplifier output, with output current limited to 50 mA absolute maximum.
7 +VS power_in Positive supply; single-supply operation from +4.5 V to +36 V or dual supplies from ±2.25 V to ±18 V, bypassed close to the pin with a 0.1 µF ceramic capacitor.
8 RG passive Gain setting pin; for gains greater than 1, a gain resistor is placed between pins 1 and 8, with gain G = 1 + 49.4 kΩ/RG.

CAD (KiCad official)

  • Symbol: COS620ARZ
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cos620arz-etched.step / cos620arz-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos620arz.step / cos620arz.glb are the bare package body.
