The ADAU1401 is a complete single-chip audio system with a 28-/56-bit audio DSP, ADCs, DACs, and microcontroller-like control interfaces. Signal processing includes equalization, cross over, bass enhancement, multiband dynamics processing, delay compensation, speaker compensation, and stereo image widening. This processing can be used to compensate for real-world limitations of speakers, amplifiers, and listening environments, providing dramatic improvements in perceived audio quality.

Its signal processing is comparable to that found in high end studio equipment. Most processing is done in full 56-bit, double precision mode, resulting in very good low level signal performance. The ADAU1401 is a fully programmable DSP. The easy to use SigmaStudio software allows the user to graphically configure a custom signal processing flow using blocks such as biquad filters, dynamics processors, level controls, and GPIO interface controls.

ADAU1401 programs can be loaded on power-up either from a serial EEPROM through its own self-boot mechanism or from an external microcontroller. On power-down, the current state of the parameters can be written back to the EEPROM from the ADAU1401 to be recalled the next time the program is run.

Two Σ-Δ ADCs and four Σ-Δ DACs provide a 98.5 dB analog input to analog output dynamic. Each ADC has a THD + N of −83 dB, and each DAC has a THD + N of −90 dB. Digital input and output ports allow a glueless connection to additional ADCs and DACs. The ADAU1401 communicates through an I2C® bus or a 4-wire SPI port.

Features and Benefits

EVAL-ADUSB2EBZ "USBi"
  • Digital I/O: USB input, I2C/SPI output
  • DC Supply: 5 V (USB) 

Product Detail

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.


USBi

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.
