描述
The QCIOT-DA7212EVZ Click Board™ demonstrates the functionality and performance of the DA7212. The DA7212 is an ultra-low power audio codec designed for portable audio devices. Comprehensive analog mixing and bypass paths to the output drivers are available.
Digital audio transfer to/from the external processor is via a bidirectional digital audio interface that supports all common sample rates and formats. The device may be operated in slave (target) or master (controller) modes using the internal PLL, which may be bypassed if not required. To fully optimize each customer application, a range of built-in filtering, equalization, and audio enhancements is available. These are accessible by the processor over the I2C serial interface.
The board operates as an audio development expansion for a host MCU board and allows for the development of a complete audio input/output solution by including an on-board speaker and microphone. It also features input and output jacks for connecting to external devices. The Click Board connects to a host board via the Renesas mikroBUS™ interface.
