• Serial Ports support for ADAU1467 & ADAU1462

    As per the ''Selection table for SigmaDSP audio processors' Serial I/O Ports supported for ADAU1467 & ADAU1462 is mentioned as 12 ports for input and output.

    But while referring Data sheet, serial ports supported is 4 only. Please clarify…

  • RE: ADAU1466 vs. ADAU1462 Code Compatibility

    One caveat is that they are not interchangeable from an external (SPI / I²C) programming point of view: For example, to access 0x3000-0x4FFF of DM0 (a memory range valid for the ADAU1452 and all ADAU146x devices), the address to use on the slave interface…

  • RE: "ADAU1462" actually appears to be an ADAU1466

    There is no manufacturing defect.

    I should have added "or the datasheets seem to be incorrect about the slave interface memory map of the ADAU1462/3".

    These are built from the same die and the memory is there but…
  • ADAU1462-150 PLL and other settings


    I was starting implementation for the ADAU1462-150 and came accross some points that are unclear for me.

    1) The datasheet shows in Table 20 on page 29 the predivider and feedback divider settings.
    The table states for a 12.288MHz input a setting of…

  • SigmaStudio 4.1, ADAU1462 bug report

    Hi there,

    SigmaStudio 4.1, RealTimeVariant for ADAU1462 still doesn't work. VariantEditor window doesn't opening.

    For ADAU1452 all is OK.

    Best regards,

  • Timing parameters S/PDIF on the ADAU1462


    I would like to know more about timing parameters of the S/PDIF input on the ADAU1462.

    On page 11 of the datasheet (rev. C) there is only a table regarding the Audio Sample Rate.

    I would like to know about the Skew timing and other parameters of…

  • ADAU1462 reset and idle power consumption

    Can you please advise if the datasheet power consumption figures are correct for reset and idle over TA = −40°C to +105°C.

    It states the maximum is 559mA !!


  • ADAU1462 a sample rate of 192 kHz

    I'm working on a project  using ADAU1462 and AD1938 to du  a sample rate of 192 kHz  but there are a question ---  ripple

    bu use 48 kHz sample rate is very good

    I use sigmastudio

    and  AD1938  also Configured to 192kHz

    I am very troubling, How can i Configured…

  • ADAU1462 data memory size


    According to the datasheet for the ADAU1462, the data memory size is 48kWords.

    However, according to the compiler output window in Sigma Studio 3.17:

    ADAU1452 - DM0: 20480, DM1:20480, PM: 8192 (OK)

    ADAU1462 - DM0: 20480, DM1:20480, PM: 16384…

  • ADAU1462/1466 data sheet, several issues.

    I am referring the latest ADAU1462/1466 data sheet Rev.C.

    Please let me confirm below. If there are document anomalies, could you modify them in future?


    1. Digital Input voltage, no noise margin

    Is following specification correct?
