 * \brief c2x30W Amp Click example
 * 
 * # Description
 * This application is audio amplifier.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes GPIO driver and enables the device.
 * 
 * ## Application Task  
 * Mute output for a period of 3 seconds, then keep it unmuted for a period of 10 seconds. 
 * After that, checks if over current fault, over temperature fault or too high DC offset fault occurred.
 * 
 * ## NOTE 
 * When under or over voltage condition occurres the output goes to high impedance state,
 * but the FAULT pin will not be asserted.
