TAS2110EVM: TAS2110 Input volume is too high

Part Number: TAS2110EVM
Other Parts Discussed in Thread: TAS2110

Hello, 

I recently applied for a development board for TAS2110.

When debugging with PPC3, I found that if the input volume is too high, the output will be intermittent, which is just like the chip is constantly resetting.

Would you please tell me if there is any restriction on the input volume of TAS2110?Or can you adjust a register to solve this problem?

Thank you very much!

    Hi Zhou,

    What speaker are you using? Are you using the default configuration?

    Could you please check the latched flags on PPC3 to verify if there is any protection being triggered? You can do this from Device Control panel, top right corner, the IRQ button.

    Hi,Ivan,

    I tried using a 3W/5W speaker output and the result was the same.

    The configuration of the IRQ in case of a failure is shown in the following screenshot.

    And the Live is Device Power Down.

    Excuse me, what is the reason for this? Is there any way to solve it?

    Hi Zhou,

    Based on the IRQ capture you attached, there are several error flags being triggered:

    • Limiter Max Attenuation means the limiter has reached its maximum attenuation, so perhaps the input signal is too high.
    • BrownOut Active and Detected means there was a power loss during the test.

    So I have two questions:

    • What is your limiter configuration? This feature is disabled by default, if it's being triggered it means you have modified the default settings.
    • What is your brownout protection configuration?
    • Can you inspect VBAT voltage during your test? I'd like to check if there is any voltage droop during your test.
