Potentiometers
The MAX5527/MAX5528/MAX5529 power up and func-
tion after power-up with the wiper position set in one of
three ways:
1) Factory default power-up position, midscale, adjustable
2) A newly programmed power-up position, adjustable

3) A new programmed power-up position, locked wiper
The wiper is set to the factory default position at power-
up (midscale, tap 31). Connect PV to GND or leave
floating to continue powering up the wiper position at
midscale. See Table 1 for the default and one-time pro-
gramming options.
