TAS2505-Q1: Power On Sequence ?

Lee, Sam

Part Number: TAS2505-Q1

Hello team,

A customer asks about the power on sequence of TAS2505-Q1, which is different from Application reference guide. Can you explain if it's okay or which risk is expected?

    Sequence : 1.8V (AVDD, DVDD)   -->   3.3V(IOVDD, SPKVDD)

Thanks,

Sam Lee

    Hi Sam,

    Please follow the documentation recommendations. The behavior in terms of initialization, POR, etc can be unpredictable otherwise.
    We cannot recommend different instructions than the specified on the documentation.
