• ADAU1401 IIS  connection problem---- how to deal with the four channel IIS serial data input to ADAU1401

    If I have four channel I2S serial data input to ADAU1401 , how should I deal with the INPUT_LRCLK & INPUT_BCLK Pin ? Because I have 4 pair of LRCLK&BCLK ,but ADAU1401 only one pair of LRCLK&BCLK.

  • ADAU1401 debug without Evaluationboard?

    Hello,

    I would like to use ADAU 1401 for my application.At the moment there is one question left:

    Is it possible to debug ADAU1401 without an evaluationboard?

    Kind regards

  • Adau1401 is dead

    Hi

    I have serious problem with ADAU1401. In general it does not start I2C communication and does not ask eeprom for data despite it has selfboot pin high and wp connected to eeprom and low level. I make the reset and power hard reset as well. Nothing…

  • ADAU1401 WriteBack Trigger

    Hi,

    I want to trigger a Write Back action on the ADAU1401 to save volume control and filter parameters.

    Rather than try to build a voltage monitoring system that pulls the WB pin high when the voltage rail is dropping, I thought it might be possible…

  • ADAU1401 crystal oscillation

    The ADAU1401 is used in car infortainment project together with NXP tuner. The main problem is from the DSP Crystal frequency, as long as the crystal oscillates it will affect the FM freq at 98.3MHz. I am using 12.288MHz as MCLK. Any alternate way to…

  • ADAU1401 MCLK and BCLK

    I am currently working on a project with the adau1401. I going to be using an spdif receiver connected to an ASRC and then to the ADAU1401. The ADAU1401 will be doing some filtering and outputting i2s to a set of three DACs. I'm having an issue conceptually…

  • ADAU1401 register readback

    Hi,

    I want to read a value using the readback function in SigmaStudio using a microcontroller connected to the I2C bus.

    For testing purpose I have connected a DC value to the readback module.

    When I press the READ button the module correctly shows the…

  • ADAU1701 / ADAU1401 SPI Interface Timing

    The ADAU1701 and ADAU1401 data sheets specify maximum SPI clock CCLK frequency as 6.25MHz.

    The data is available on the COUT pin up to 101ns after the CCLK falling edge according to the table above, but the Figure 3 below clearly shows this delay as…

  • adau1401 for Echo Cancelling

    Hi,

    I need to design an echo cancelling circuit for a speakerphone system. I would appreciate if someone can tell me if the ADAU1401 is appropriate for such application. Is the sigma DSP inside this CODEC powerful enough for echo cancelling.
