The EVAL-ADAU1966Z and the EVAL-ADAU1962Z evaluation boards allow the user to evaluate the ADAU1962, 12 channel Digital to analog converter (DAC) or the ADAU1966, 16 channel DAC. The evaluation board will supply bit clock, LR clock and master clock and will except either 6 or 8 dual channel I2S data streams or multiple TDM (Time Division Multiplexed) data streams. The board has an S/PDIF receiver with RCA and optical connectors, as well as a discrete serial audio interface. Analog outputs are accessible via two db-25 connectors and channels 1 and 2 can be routed to an on-board headphone driver with the output on a stereo TRS Mini jack.

The EVAL-ADAU196x can be controlled through either an I2C or SPI interface. A small external interface board EVAL-ADUSB2EBZ, also called USBi, connects to a PC USB port and provides either I2C or SPI access to the evaluation board through a ribbon cable. The USBi is included with the evaluation board. A graphical user interface (GUI) program, the Automated Register Window Builder, is provided for easy programming of the chip in a Microsoft® Windows® PC environment. The evaluation board allows demonstration and performance testing of most ADAU196x features, including high performance DAC operation.



The Analog Devices USBi “USB Interface” (EVAL-ADUSB2EBZ) board is the interface between your PC's USB port and SigmaDSP hardware's data input pins. This interface can be used with any evaluation board which includes an External SPI/I²C header (Aardvark Header). The EVAL-ADUSB2EBZ board is capable of both SPI and I²C communication (which is user selectable) and can supply IOVDD of either 3.3V or 1.8V.The USBi interface is powered from the computer's USB port.

To Install the USBi Board:
  • Connect the USB cable to the USBi Board a spare USB port on your PC.
  • The Windows “Found New Hardware Wizard” will launch.
  • Choose “Install from a list or a specific location” and click “Next”.
  • Select “Search for the best driver in these locations” and Check the box for “Include this location in the search.”
  • Press the “Browse” button and locate the appropriate driver file in the SigmaStudio application folder (default folder is C:\Program Files\Analog Devices Inc\Sigma Studio\USB drivers): Select the CyUSB.inf file.
  • Click “Continue Anyway” if you're prompted with “This software has not passed Windows Logo testing.”
Using USBi in SigmaStudio:
To communication between SigmaStudio and the USBi board, a communication channel block must be added to the Schematic design. To locate the block, select the Hardware Configuration Tab, int the ToolBox or Tree ToolBox window choose the “Communication Channels” category, and select the USBi block.


This block provides connections for multiple processors (ICs / DSPs), allowing you to use multiple processors in a single design. This block allows you to explicitly specify both the communication protocol (SPI or I²C) and the part's address, I²C address or SPI clatch line. The DSP hardware's address must match the block's selected address for communication to function properly. See the parts data sheet for more information about addressing (e.g. ADR_SEL, ADDR0, or ADDR1 pins). The default USBi protocol is I²C, to enable SPI, you must first select an SPI address in the block's drop down menu and then perform three write operations (e.g. press the write button the Register Read/Write Window 3 times). The USBi hardware has LEDs which indicate the current mode, I²C or SPI.
