Top Performance LA4446 Stereo Audio Amplifier Circuit
LA4446 is of similar series IC as LA4440, but it is meant for dual or stereo 5.5Watt RMS outputs. While 4440 gives 6Watt outputs at dual mode, this gives almost same but with much smaller package size. The IC package is mall but it provides same functionality and special features like LA4440. These are,
- Low pop noise at power ON/OFF time
- Good ripple rejection: 46dB(typ)
- Good channel separation
- Low residual noise (Rg=0)
- On chip protectors as Thermal protector, Over-voltage/Surge Protector, and pin short protector
The below circuit is the application circuit of LA4446 IC.
