EVAL-ADAU1466

Product Details

This device is suitable for evaluation of, and software development for, the ADAU1466 and ADAU1462 SigmaDSP processors. Note that the ADAU1466 and the ADAU1462 are functionally identical, except that the ADAU1466 has more program and data memory than the ADAU1462. When using this evaluation board to evaluate the ADAU1462, in the Setting Up Communications in SigmaStudio section, select the ADAU1462 block rather than the ADAU1466. Performing this action informs the compiler to limit the amount of memory allocated to match the ADAU1462. All other procedures and instructions in the user guide are identical for the ADAU1462 and ADAU1466.

This evaluation board provides access to the digital serial audio ports of the ADAU1466, as well as some of its general-purpose input/outputs (GPIOs). Analog input and output is provided by the AD1938 codec that is included in the evaluation kit. The ADAU1466 core is programmed using Analog Devices, Inc., SigmaStudio^® software, which interfaces to the evaluation board via a USB interface (USBi). The on-board EEPROM can be programmed for self boot mode. The evaluation board is powered by a 6 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 evaluation board includes connectors for external analog inputs and outputs, and optical Sony/Philips Digital Interface (S/PDIF) interfaces. The master clock is provided by the integrated oscillator circuit and the on-board 12.288 MHz passive crystal.

For full details, see the ADAU1466 and AD1938 data sheets, which must be used in conjunction with the user guide (UG-1135) when using the evaluation board. EVAL-ADAU1466 requires SigmaStudio software version 3.15 or later.
