 * \brief Dac5 Click example
 * 
 * # Description
 *
 * This demo example sends digital signal to one of the outputs and converts it to analog
 * 
 * The demo application is composed of two sections :
 *
 * ## Application Init
 * Initializes driver init, tests communication and configures device for measuring
 *
 * ## Application Task
 * Sets the channel H with different values and logs the expected output on USB UART
 *
 * ## NOTE
 * In order to improve the accuracy, measure the voltage on the click board VrefIN SEL jumper and set it as VREF below.
