Operation of the digital potentiometer in divider mode results
in a more accurate operation over temperature. Unlike rheostat
mode, the output voltage is dependent mainly on the ratio of
the internal resistors RWA and RWB and not on the absolute
values; therefore, the temperature drift reduces to 5 ppm/°C.
