DA7218-EVAL

User Guide DA7218 EVB User Guide – Rev1.1 DA7218 Ultra Low Power Codec Introduction The DA7218 Evaluation Board (233-02) has been designed to allow measurement and evaluation of the DA7218 device. It connects to the Digital IO Board for USB control and for digital audio input/output via the digital audio interface. All analogue audio codec functionalities are contained within the DA7218 Evaluation Board (EVB). The Digital IO Board user guide accompanies this document. The EVB is supplied with a USB memory stick containing various documents and a GUI to allow the user to control the DA7218. The GUI is called SmartCanvas™. It uses a simple graphical interface, allowing the DA7218 to be controlled via a USB port of a PC. The SmartCanvas user guide accompanies this document. The EVB has a number of jumper links to enable the user to change the system configuration and to allow them to make appropriate measurements, although, in reality, few jumper links are required to be altered for standard operations of the device.

The hardware solution is based upon two PCBs: - “Digital I/O Board” - “DA7218 Performance Board 233-02-C” The user guide for the Digital I/O board accompanies this document. DA7218 EVB User Guide_Rev1v1 Page 3 of 9 User Guide DA7218 EVB User Guide – Rev1.1 Hardware The DA7218 Evaluation Board consists of the DA7218 device, the essential external components and analogue interconnects. This board could also be used in standalone or as a module for a customer development platform. Figure 2: DA7218 – Default Jumper positions shown in Red (power) and Blue (signal) Note: The EVB has been configured by default to work from the digital I/O board’s on-board regulators.
