  • TIC12400-Q1: Internal ADC ref voltage

    TI Thinks Resolved
    Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TIC12400 Hello Experts, I found the internal ADC of TIC12400's reference voltage is marked as 6V, may I know where does this 6V come from? Because I just considered 6V is not a common ref voltage…

  • TIC12400-Q1: The switch status of the 12400 chip collection cannot change with it

    TI Thinks Resolved
    Part Number: TIC12400-Q1 Other Parts Discussed in Thread: TIC12400 Hello experts We used TI's TIC12400 chip. After it was loaded and used for a period of time, a fault occurred. The switch status collected by the 12400 chip could not follow the change.…
