TAS5411-Q1: Questions about both data sheet and EVM.

Part Number: TAS5411-Q1

Hello,

I have questions about both TAS5411-Q1 data sheet and EVM.

-DataSheet (Page.4)

7.1 Absolute Maximum Ratings

The max value of the input voltage for SCL, SDA, STANDBY pins are 5 V,

but the values of V (IH_SCL) , V (IH_SDA) listed on the next page are MAX 5.5 V.

Are the Absolute Maximum Ratings of SCL, SDA, / STANDBY pins the same value as For IN IN, IN _ P, and MUTE pins,MAX 6.5 V?

-TAS5411EVM User's Guide (Page.9-10)

Is L1 (Inductor) placed on the power line (VIN) of TAS5411 EVM a filter for power supply?

Thank you for your help.

Best Regards, Orobianco

  • Hello Orobianco! Sorry for any confusion. Absolute values are typically across a broad base of conditions. The Operating parameters are typically set based on an actual operational configuration / design, and are values that the device is actually tested to.

    Gregg, Can you add any further context to this that would be helpful?

    Thanks, Jeff
  • Hello , Mr.Jeff!

    Thank you for the immediate reply.

    I can understand your comment.

    But in this case, the maximum voltage of the recommended operating condition exceeds the maximum voltage of the absolute maximum rating.

    I understand that the maximum voltage of the absolute maximum rating will cause damage to the device if I use it exceeding that value,so I think that the relationship of " the maximum voltage of Absolute maximum rate > the maximum voltage of recommended operating voltage is correct, how is it?

    Also, Would you please answer the following question as well ?

  • Hello Orobianco! Thanks for the additional feedback.

    Gregg will take a look at you questions for further clarification. Thanks, Jeff
  • Hi Orobianco,
    The filter on the power supply is for EMI filtering.
  • Hello , Mr.Scott!

    Thank you for your reply. I understood your comment.

    However, I have not yet solved the following question.

    Woulud you please  answer bellow question?

    The maximum voltage of the recommended operating condition exceeds the maximum voltage of the absolute maximum rating.

    I understand that the maximum voltage of the absolute maximum rating will cause damage to the device if I use it exceeding that value,

    so I think that the relationship of " the maximum voltage of Absolute maximum rate > the maximum voltage of recommended operating voltage is correct, how is it?

    Is this value really correct?  => 7.1 Absolute Maximum Ratings         The max value of the input voltage for SCL, SDA, STANDBY pins are 5 V.

    Thank you for your help.

  • Orobianco,
    It seems you have found an error in our datasheet. The absolute maximum on the SCL, SDA, and STANDBY pins is 5.5Vdc max. We will update this.
  • Hello,Mr.Gregg.

    Thank you for your reply.
    I have resolved my issue with your answer.

    I expect this data sheet to be updated promptly.

    Thank you for your help.
    Best Regrds,Orobianco.
