Hello,

Is it possible to remove HP/Lineout popsound effect in TAS5739? I have already consulted Register 0x1A (Start-Stop Timing) but couldn't get a solution. Thank you

    Hi, Turgay,

    Nice to hear from you!

    Register 0x1A is only for the class-D outputs, it does not affect the HP/Lineout.

    Normally, the output should be pop-free. Some reasons for pop may be due to the driving stage popping. In that case, please keep the HP/Lineout muted until the driving stage has stabilized, and then enable the HP/Lineout.

    On the EVM, we have used 1 uF input dc blocking caps, and 1 uF caps for the charge pump as well. Do you have an EVM to listen to the pop on that?
