The ADAU1361 is a low power, stereo audio codec that supports stereo 48 kHz record and playback at 14 mW from a 1.8 V analog supply. The stereo audio ADCs and DACs support sample rates from 8 kHz to 96 kHz as well as a digital volume control. The ADAU1361 is ideal for battery-powered audio and telephony applications.
The record path includes an integrated microphone bias circuit and six inputs. The inputs can be mixed and muxed before the ADC, or they can be configured to bypass the ADC. The ADAU1361 includes a stereo digital microphone input.
The ADAU1361 includes five high power output drivers (two differential and three single-ended), supporting stereo headphones, an earpiece, or other output transducer. AC-coupled or capless configurations are supported. Individual fine level controls are supported on all analog outputs. The output mixer stage allows for flexible routing of audio.
The serial control bus supports the I2C and SPI protocols. The serial audio bus is programmable for I2S, left-/right-justified, and TDM modes. A programmable PLL supports flexible clock generation for all standard integer rates and fractional master clocks from 8 MHz to 27 MHz.

Product Details
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, in 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 catch 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.
