 * 
 * # Description
 * This application integrated bi-directional analog output current sensors.
 *
 * The demo application is composed of two sections :
 * 
 * ## Application Init 
 * Initializations driver init.
 * 
 * ## Application Task  
 * Reading ADC data and converted current mA data from device and logs it to device.
