Pam 8403 Audio IC details,pinout,voltage and datasheet

The PAM 8403 is a high performance and high efficient Class-D audio amplifier IC that can output 3W+3W Sound power with +5V voltage.


It is upto 90% efficient and is useful for portable applications such as cellphone speakers etc

I have a stereo speakers system from philips that uses this ic and it is really power efficient and the sound output is high quality with no noise. In my automobile, i can’t tell if the amp is on or not because there is no noise from speakers, i can’t guarantee that there will be no noise if this amp is powered from mains supply

This amplifier with a subwoofer should be enough for your small room
