• ADAU1466 second page addressing

    Hi all, 

    We are implementing the interface for controlling an ADAU1466 from an MCU and we've found that the second page addressing is quite inconvenient. This is because the addresses of parameters that live on the second page can not be made relative…

  • SigmaDSP ADAU1466 pink noise generator

    Hi.

    Expert.
    I'm checking the pink noise generator of SigmaDSP ADAU1466 and it's weird. Please help.

    I tested the ADAU1466 noise generator and the Audio Precision output.

    CH1_3: Audio Precision output (Pink noise) -> AP measurement
    CH1_5: Audio…

  • ADAU1466 PINK NOISE GENERATOR

    Hello.

    I used ADAU1466 + SIGMASTUDIO 4.2 to create PINK NOISE GENERATOR as shown in the image below.

    However, it operates slightly differently from PINK NOISE output from other devices. In the image below, green is the PINK noise output by general equipment…

  • adau1466 pll max frequency

    Dear all,

    I'm not able to reach core max frequency with my adau1466.

    Xtal = 12.288

    predivider = 4

    pll mult = 80

    12.288/4*80 = 245.76 MHz

    If i try to run faster, the pll locks and unlocks few seconds later.

    What do you think about this issue ? does…

  • ADAU1466 192k Sampling

    I am trying to setup the clock control for 192k sampling.  In this case I need the MCLK OUT to be Base_Fs x 256 (12.288 MHz).  I am using CLK GEN1.  Currently I have the PLL CTRL1 to Divide by 8 and the PLL CTRL0 set to 96.  In this case it seems that the…

  • ADAU1466 overheat ?

    Hi !

    I would be interested in what happens to an ADAU1466 if it overheats, to compare that to the strange behaviour that I am currently experiencing.

    In the current revision of my DSP board, I am still using the same supply scheme as on the eval board;…

    Is an Altium Library available / planned ?

  • External Delay with ADAU1466

    I have connected IS62WVS5128GBLL - 4MBit SRAM to ADAU1466. It used for block ExtDelay. Slave is 5, SPI Mode 3. It works well (only) with 13,5MHz. RAM size 524288 bytes.

    I have connected ExtDelay to channel 0 and channel 1. It works well, in both chgannels…

  • ADAU1466 and Arduino communication

    Hi,

    I'm trying to make my ADAU1466 eval board to communicate with my Arduino ATMEGA2560. I'm using Arduinos code "i2c_scanner" that should be able to scan and detect the I2C addresses for slave devices. I am not getting anything from the scan, so i'm…

  • ADAU1466 and I2C Operation

    I would like to find someone that operates an ADAU1466 via the I2C, instead of the SPI interface, to answer a few basic questions.  For example, if a design is created in SigmaStudio, then loaded into the flash on the Eval board with the SPI interface…
