    Wink H,W or L ... same limits !!!

    Sorry, Roger

    it was :

    " W - Wiper of the Potentiometer. This pin is the wiper of the potentiometer. Its position on the resistor
    array is controlled by the 3-terminal control port. Voltage applied to the wiper cannot exceed the powersupply
    voltage,
    VCC, or go below ground."

    that means voltage on the wiper must not Exceed 5 Volts ... so, your output can't safely exceed 24 + 5 - .8 ( By 500 ! ) = 28 v

    you tell 25 to 30v out ... that's 2 v too much !!! I'm oK, only two "little volts" ... but too much ...

    I told you on another thread the DS couldn't bear the voltage you want !!!

    Why insist on using 32 Bits when you're not even able to deal with the first 8 ones ??? ehhhhhh ...

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
