• SPI control commands for AD1934

    I am trying to program the DAC for AD1934, I tried downloading the evaluation software from EVAL-AD1938 which is the nearest eval that is linked from AD1934,

  • AD1934

    Hello,

    I'm using the codec ad1934 to have 2 channels with I2S protocol but I can't find several informations in the datasheet. I'm using a 16,934 mHz crystal oscillator for the mclk but it doesn't run. All the register values are at 0x00.…

  • ADAU1467+AD1938 + AD1934. How to get 8 balanced (16 unbalanced) independent channels?

    Hello, Dave.
    I have ADAU1467 + AD1938 CODEC + AD1934 DAC.
    How to get 8 balanced (16 unbalanced) independent channels  output, and 2 balanced (4 unbalanced) channels at the input.
    How to make ADAU1467 and AD1938 TDM signals understand?
    Or can I use SDATA IO…

  • AD1934 recommended Loop Filter component values

    Hello,

    I'm using an AD1934 DAC for my product and the datasheet recommends some component values for the Loop Filter (see https://www.analog.com/media/en/technical-documentation/data-sheets/AD1934.pdf p.25, Loop Filter for LRCLK)

  • total delay of ADAU1977 and AD1934

    Hello support team,

    I want to clarify total delay of ADAU1977 and AD1934 (at fs=48kHz) .
    Group delay is specified in each datasheet as 22.9844/fs and 25/fs respectively, but how many extra sampling clocks do I need to assume for "Serial Auto Port" portion…

  • RE: AD1934 interface with Microcontroller - Not able to hear anything on DAC output

    Hello memo,

    Can you show us your schematic? For the PLL to lock you need to have a valid master clock or the registers set to route the LRCLK to the PLL input. Then you need the correct PLL filter. Then all the correct power and ground. I have seen poor…

  • Making the AD1934 give output

    I am trying out a weird combination to make the AD1934 work.

    This is my register configuration:

    PLL clock control 0 : 0b10001000 (Input 256xfs, 256 x fs output at MCLKO, internal MCLK enable)

    PLL clock control 1 : 0b00000000 (DAC clock source and clock…
