- Part Models
- 3
- 1ku List Price
- Starting From $5.82
Part Details
- Programmable audio processing engine 192 kHz processing path
Biquad filters, limiters, volume controls, mixing - Low latency, 24-bit ADCs and DACs
102 dB SNR (signal through PGA and ADC with A-weighted filter)
107 dB combined SNR (signal through DAC and headphone with A-weighted filter) - Serial port sample rates from 8 kHz to 192 kHz
- 38 μs analog-to-analog latency
- Four single-ended analog inputs—configurable as microphone or line inputs
- Stereo analog audio output—single-ended or differential, configurable as either line output or headphone driver
- PLL supporting any input clock rate from 8 MHz to 27 MHz
- Full-duplex, asynchronous sample rate converters (ASRCs)
- See data sheet for additional features
The ADAU1772 is a codec with four inputs and two outputs that incorporates a digital processing engine to perform filtering, level control, signal level monitoring, and mixing. The path from the analog input to the DSP core to the analog output is optimized for low latency and is ideal for noise cancelling headsets. With the addition of just a few passive components, a crystal, and an EEPROM for booting, the ADAU1772 provides a complete headset solution.
APPLICATIONS
- Noise cancelling headsets, headsets, and headphones
- BlueTooth ANC headsets, headsets, and headphones
- Personal navigation devices
- Digital still and video cameras

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.
