• RE: ADAU1452 code download

    Hello, Dave


    Thank you for your quickly response!


    We find the root cause about this issue(hardware design issue):


    Root cause:

         The MCU control the ADM811 pin 3(MR), and the ADM811 pin 2(Reset) connct to the ADAU1452 reset pin.

    When we pull high…

         It may not matter, but I did notice a difference in reset circuits for the two boards.  The 1701MINIZ board processes the /RESET from the USBi through the ADM811 (into pin 3 and out pin 2):

  • RE: ADM809T testing question

    Hi Kevin,

    As the threshold of the devices are all tested during production test, it’s unlikely an issue with the device.

    I would advise the customer to check the grounding of the scope, try measure ADM811’s VCC and RESET by referencing the scope ground…

  • ADM811 resistive divide usage


    ADM811 is very low consumption current device.

    Can ADM811 use resistive divided input?

    I would like to spend 1mA for resistor.

    (input voltage is 24V, 100uA enough?)

    ADI has more suitable device, I know.

    Sorry I could not select other device.

  • Output Voltage of RESET pin of ADM811LARTZ

    Hello support people,

    I have a question about the output level of ADM811L RESET pin.

    In the page-3 of ADM811 datasheet(Rev.G), spesification of minimum level of "high" output is wirtten as "Vcc x 1.5".

    According to this, if I use…

  • RE: ADAU1467 Please let me know the correct timing in the system initialization sequence.

    Hello takumi3952,

    This is shown in the Figure 14 diagram. Basically, until the power has come up and stabilized and the internal level shifters start functioning, then the master clock is allow to reach the PLL. At that point the state of the reset pin…

  • RE: 1452 ASRC noise

    Hi Dave,

    this is not a solution for the first lock after powering up the ADAU.

    There is no problem with the mute function (mute ASRC when lock is lost) if at least one lock is done!

    After this you can plug-in/out the toslink without any pop noise.…
