COS6112

COSINE · Audio Amplifiers · MSOP-10

COS6112 from COSINE, in a MSOP-10. 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 Vo1 output Vo1 is the audio output for channel 1.
2 IN1- input Negative input for channel 1.
3 IN1+ input Positive input for channel 1.
4 BYPASS input Tap to the voltage divider for the internal mid-supply bias; connect a 0.1µF to 1µF low ESR capacitor for best performance.
5 GND power_in Ground connection for the device.
6 SHUTDOWN input Puts the device in a low quiescent current mode when held high; high-level shutdown voltage is >60% VDD and low-level is <25% VDD.
7 IN2+ input Positive input for channel 2.
8 IN2- input Negative input for channel 2.
9 Vo2 output Vo2 is the audio output for channel 2.
10 VDD power_in Power supply; DC supply voltage is 2.5V to 5.5V, with absolute maximum VDD to GND of 6 V.

CAD (KiCad official)

  • Symbol: COS6112
  • Footprint: Package_SO:MSOP-10_3x3mm_P0.5mm
  • 3D model: MSOP-10 (KiCad packages3D, STEP)
  • 3D model files: cos6112-etched.step / cos6112-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); cos6112.step / cos6112.glb are the bare package body.
