TLV320DAC32 / Volume Control

Kuramochi Tadahiko

Hi,

My customer would like to control volume of the digital input signal.

I think that it can do from seeing the figure 19 and SIMPLIFIED BLOCK DIAGRAM of the datasheet.

However it looks like that it cannot do from seeing the figure 34.

Could you make sure whether they can do it?

Best Regards,

Kuramochi

    Hi, Kuramochi-san,

    AUDIO DAC DIGITAL VOLUME CONTROL section of datasheet explains how the digital volume control works.

    Page 0 / Registers 43 and 44 can be used to control the DAC digital volume.

    Please let me know if you have questions or comments.

    Best regards,
