Theory

    In this project, the main component is the TDA2005R which is a class B dual audio power amplifier in the Multiwatt11 package. TDA2005R can be configured for Bridge or Stereo applications.

TDA2005R can operate with a supply voltage ranging from 8 to 18 volts and has a closed-loop voltage gain of about 50dB.

For this project, I am using the Bridge configuration.

Note: When using a Multiwatt11 package always use a heat sink
