    digital pot resolution

    Why digital pots come with low resolution? Can they not implement R-2R ladder as in DAC to improve their resolution?

    Hi,

    I don't know. Maybe because of cost, size, power requirement..

    If you want a DAC, you are free to use a DAC.

    Re: digital pot resolution

    The primary use of digital pots is for circuits that need a variable resistor or a true potentiometer which doesn't work with R-2R ladder. The resolution is respectively limited by the feasible number of analog switches.
