COS4890SR

COSINE · Audio Power OpAmps · SOP-8

COS4890SR 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 SHDN input Shutdown control: the device enters shutdown mode when a logic low is applied (VIL max 0.4V, VIH min 1.2V).
2 BYPASS passive Bypass capacitor pin which provides half-supply filtering.
3 +IN input Positive input of the first amplifier, connected to the half-supply common mode voltage.
4 -IN input Negative input of the first amplifier, connected to the load and to the input resistor RIN and feedback resistor RF.
5 VO1 output Negative output, connected to the load and the feedback resistor RF.
6 VDD power_in Analog power supply, 2.5V to 5.5V recommended operating range (6V absolute maximum).
7 GND power_in Ground.
8 VO2 output Positive output, connected to the load.

CAD (KiCad official)

  • Symbol: COS4890SR
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: cos4890sr-etched.step / cos4890sr-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos4890sr.step / cos4890sr.glb are the bare package body.
