• AD1854 to AD1852

    Hi

    My customers chose the AD 1854 as an alternative to the AD 1852, which became an EOL.
    The customer buffered the audio output of the AD 1854 and the customer gave control signals and data to the AD 1854 in the same way as the AD 1852.
    However, AD 1854…

    converter of Analog Devices. The DAC in question is the AD1854KRS.
    I’ve downloaded the datasheet from your website. In my project I have no
    interest in controlling…

    Falk Hatzfeld (GERMANY)

    Message: 9182    Compared to the 537 STAMP the 537 EZLITE has an audio DAC (and ADC) polulated. Is it possible to use this AD1854 with uClinux as well? (Driver / settings)?

  • BF-537 EZKIT driver for AD1854 or how to use AD194x driver

    Hi

     

    I have BF-537 EZKIT.  I would like to use the onboard DAC AD1854.  I saw posts people had success using the AD194x driver, but unfortunately nobody has actually documented what needs to be done.

     

    I have compiled an image, (attached .config + .config_custo_linux…

  • RE: Low Volume Level at output of BF537

    Hi,

    To confirm, you are driving the AD1854 DAC with an I2S format stream with a signal of 0 dBFS as generated by your dScope? You have measured a 1.4 dB drop at the output; the AD1854 should be putting out 2 V RMS (6 dBV) under this condition, within…

  • RE: BF537 Audio talkthrough in uClinux

    AD1854 and AD1871 are not supported directly by the Linux BSP for Blackfin. You may have to port or develop according to  an existing sound driver, such as AD1836.
