• ADAU1777 registers can't write

    Hello sir,

        We now use adau1777 , we use pll,we write our setting into 0x00 - 0x05,and read 0x06.the PLL has locked.but we also can't write other registers. the setting of 0x00-0x05 is as below:

      We have read the 0x00-0x05 and ensure that the value…

    Is there anyway to get samples of audio straight from ADAU1777 to my PC? with or without SigmaStudio/


  • RE: ADAU1777 registers read and write

    Hello Brom,

    Make sure you have the correct master clock coming in and then check that the PLL is locked and that is located in register 0x06. Then you have to turn on the Main Clock Enable and set the dividers properly and then take the clock source from…

  • RE: ADAU1777 I2C read timimg manual questions


    What I am saying is that the master can and should send the ACK. However, the 1777 does not care if the ACK happened or did not happen. The master will send the ACK and if that was the last byte of the read then the master will stop the transaction…

    Hi sir 

    my customer feedback as below  , Please help with these questions

    We are developing a prototyping platform for true wireless hearable products. The platform uses an ADAU1777 codec with 4 digital pdm microphones. The CLK_OUT pin is used of course…

  • ADAU1777 question

    Dear Sir,

    ADAU1777 can support up to 768KHz that was mentioned in datasheet as below:

    "Fast (up to 768 kHz) and slow processing paths"

    So, ADAU1777 output sample rate can support 384KHz? 

    But according to datasheet described that :

  • ADAU1777 I/O

    Im trying to work with ADAU1777Z (EVB) with 192kHZ using 4 inputs 2 outputs.
    For some reason I can only get 2 inputs and 1 output and using and external DSP (with I2S).
    Can you help me understand what not all inputs and outputs work with 192kHZ?

  • Oscillator using ADAU1777



    I am working with ADAU1777 for my application.I would want to know if there is any way that could help me generate an oscillator by connecting the DAC outputs to the ADC inputs to create a positive feedback,which could make it oscillate.
