 * 
 * # Description
 * This range is suited for audio and/or speech applications.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializes the driver and logger and sets the digital potentiometer.
 * 
 * ## Application Task  
 * Reads the AN pin voltage and displays the results on the USB UART every 100ms.
