• AD73311


    I have a audio generation system, with a CODEC TP3054. I want to replace this CODEC with AD73311. Stored audio is ".wav" files.

    Can any one help me to decide whether TP3054 can be replaced with AD73311.

  • AD73311: Power supply sequencing problem, using DVDD = 3.3V and AVDD = 5.2V

    We use two different voltages (digital 3.3V and analog 5.2V) to power
    the codec.
    With our onboard power supply we have no problems but during the
    production test we noticed a problem with the power-on-sequence.
    We have established that…

    May I use AD73311 with different DVDD and AVDD (DVDD = 3.3V and AVDD = 5V) ?


    Yes you can use DVDD=3.3V and AVDD=5V. We recommend that AVDD and DVDD are
    powered up together. On power up AVDD should follow DVDD until DVDD reaches

    What do you mean by patch for AD73322? The code is there in sound/soc/codecs/ad73311.c for AD73311/22, however support for this chip is not continued after 2011 release.

  • AD73311/AD73322 application circuit and layout


    I would like to have a information about EVAL-AD73311 or AD73322.

    I know Eval-AD73311 is obsolete.

    But we don't have any information about actual Layout and application circuit.

    Please help us.



  • AD73311 sampling noise problem


        I use ad73311 as analog-to-digital converter. the sampling data coupled severe noise. According to the sampling digital data, the max value of quantization noise is about 210 when the analog input pins connect to ground.

        however, I don't know…

  • AD73311 + LPC3250 interface and software


         We designed a system using AD73311 codec interfacing with AMBE2000 Vocoder. We interfaced AD73311 to LPC3250 SPI interface as per the AMBE2000 datasheet as shown below. But we used LPC3250 ( SPI interface ) instead of DSP micro controller.
