TAS2505-Q1: How to connect the LDO_SEL pin?

Part Number: TAS2505-Q1

Hi team,

My customer have a question about how to handle with the LDO_SEL pin of TAS2505-Q1. Because in different versions of datasheet, one recommendation(FEBRUARY 2022) is connect to GND, one(OCTOBER 2018) is ties to either SPKVDD or SPKVSS.

My customer current design is connect to VDD. Could you please tell me whether there is no problem?

Thanks!

  • Hi Iris,

    There was a fix implemented in TAS2505-Q1 related to the integrated LDO, this is the reason for different references on how to implement LDO_SEL pin.
    This fix is implemented in production material now, so they can keep this pin connected to VDD.
