AD1937 with BF533

Hi, I´m using AD1937 codec with BF533 on my own board. The problem is that DAC is not working. Digital signals are ok but the analog out is always 1.5V. Could anybody suggest me what test could I do?

Thanks

    Hi Ana,

    I will need some other information before I can give you good advice. Are you using the AD1937 in Stand Alone mode? If not, can you please provide your register settings for the AD1937? Are you able to read back the registers to confirm your settings? Can you provide the clock frequencies for MCLK, LRCLK and BCLK, please? Thanks.

    Regards,

    Coleman
