• ADAU1966


    We are trying to use this DAC to generate constant voltages to control some test equipment (so not fast changing audio, DAC was chosen by our customer). This is having to be driven by a PIC32MX in TDM 16 mode. However as the PIC32 does not support…

  • RE: ADAU1966 - important questions

    Hi Piotr,

    Yes, you are correct that you must drive the ADAU1966 in 512xFs if you do not use the PLL. If I were designing the system, I would use the ADAU1966 as the Master, with an active PLL; the ADAU1966 would then be the master of the ADAU1442. There…

  • How to connect unused SDATA inputs on ADAU1966?

    How should I connect unused SDATA inputs on ADAU1966?


    You should treat SDATA inputs on ADAU1966 the same as any unused logic/digital
    inputs, we recommend tying them to GND.
  • RE: problem with the DAI interface of 21489

    Hi ShutianXu,

    With regards to the AD1939, we have no other part with better DNR performance that would be a pin-for-pin replacement. Please look at the ADAU1966 DAC if you need higher performance; the DNR is 118 dB.


    Best regards…

  • RE: ADAU1966 Audio DAC documentation for I2C seems all messed up

    Hi Steve,

    Thank you for your attention to detail; the I2C address and R/Wb information presented in the ADAU1966 datasheet is inconsistent and in some cases incorrect. The part follows the standard protocol of R/Wb for writing and reading back register…

  • RE: ADAU1442 - Can I output two TDM16 streams?


    I'm inputting 8 stereo channels and expanding to 16 stereo outputs, processing everything at 48KHz. I'll input two TDM8 streams and have to use two ADAU1442s to be able to get 16 stereo outputs, outputting a TDM16 stream on each ADAU1442 into…

  • ADAU1966 Standalone mode limitations

    Hi gents,

    could you confirm that in standalone mode (no SPI/I2C) there is no way to make the ADAU1966 work at 96kHz sample rate?

  • ADAU1966 maximum load current

    How much current can I draw from the analog outputs? The datasheet does not
    give values for the maximum recommended currents.


    We do not specify a maximum amount of AC current that the part can supply,
    rather we say that the part should…
