• AD73322L: Frequency response

    I have a question relating to the operation of the AD73322L frequency response.

    I am testing the device with Sine wave tones ranging across the voice band
    between 300Hz and 3400Hz and
    Am finding that with a sampling rate of 16Khz, I am…
  • AD73322/AD73322L compatibility

    Can I use the AD73322L as a replacement for the AD73322 and is it pin and
    software compatible?

     

    The AD73322L is a cost reduced version of the AD73322 and is fabricated on a
    0.35um process. In 3V applications, the AD73322L is pin for…
  • AD73322L Digital loop-back mode

    Hi,

    I need to be able to enable/disable AD73322L digital loop-back mode feature for
    diagnostic purposes while the device is running.

    The device is configured in mixed mode and is properly working with audio
    samples and control words. I am able to…

  • AD73322L: symmetry within the sigma-delta modulator

    AD73322L datasheet:

    Word growth in the decimator is determined by the sampling
    rate. At 64 kHz sampling, where the oversampling ratio (OSR)
    between sigma-delta modulator and decimator output equals
    32, there are five bits per stage of the three-stage Sinc3…

  • Can I adjust Frequency Response of AD73322L?

    Can I adjust the output frequency response of the AD7332L? I am getting a quick roll off starting at 1.2KHz with a 3db down point at around 2KHz and would like to extend that cutoff to 4K or so. I understand that this is a “telecom specific” Codec so…

  • RE: SLIC interace with Blackfin

    Hi,

    We have an application note EE-193 describing the interface of  ADSP-BF535 BlackfinRegistered Processor to the AD73322L Codec. And  AD73322L is particularly suitable for a variety of applications in the speech and telephony area, including low bit rate, high…

  • How to generate interrupt using external clock and frame sync?

  • ad73322 adc sometimes 0->65535, sometimes 65535->0, per unit basis

    Hi all,

    I have a unit which uses the ad73322L analog front end. It works very well in a 3-chip cascaded formation. If I have, for example,

    8 units produced, the 1st of the 3 cascaded 73322 chips on 4 of the units will convert audio input A/D producing…

    Message: 88902   

    Dear guys,

    BF537 Ezkit has ad1854 and ad1871. I want to realize a simple 'talkthrough' application before further work. But I met some problem. By default they are…
