Negative Supply. Connect to zero volts for single supply applications.
Digital Ground.
Chip Select Input, Active Low. When CS returns high, data will be loaded into the Wiper
Register
Serial Clock Input. Positive edge triggered
Serial Data Input Pin. Shifts in one bit at a time on positive clock CLK edges. MSB loaded first.
Serial Data Output Pin. Internal N-Ch FET with open-drain output that requires external pull-
up resistor. It shifts out the previous 8 SDI bits that allows daisy-chain operation of multiple
packages
