The user guide describes the design, setup, and operation of the EVAL-ADAU1472Z evaluation board, which allows users to evaluate the ADAU1472 SigmaDSP® digital audio processor.
The EVAL-ADAU1472Z provides access to the digital serial audio ports of the ADAU1472 and some of the general-purpose input and outputs (GPIOs). The analog input and output is provided by the ADAU1761 codec included on the EVAL-ADAU1472Z.
The ADAU1472 can be configured in a variety of ways. The on-board serial flash memory can be programmed for self boot mode.
The EVAL-ADAU1472Z is powered by a 5 V dc supply, which is regulated to the voltages required on the board. The printed circuit board (PCB) is a 4-layer design with a ground plane and a power plane on the inner layers. The EVAL-ADAU1472Z includes connectors for external analog inputs and outputs and optical Sony/Philips digital interface (S/PDIF) interfaces.
For full details on the ADAU1472 and the ADAU1761, see the ADAU1472 and ADAU1761 data sheets, which must be used in conjunction with the user guide when using the EVAL-ADAU1472Z evaluation board.
