Typical Performance Curves
Power Up and Down Requirements
In order to prevent unwanted tap position changes, or an
inadvertent store, bring the CS and INC high before or
concurrently with the V
potentiometer voltages must be applied after this sequence
is completed. During power-up, the data sheet parameters
for the DCP do not fully apply until 1ms after V
final value. The V

terminal of a mechanical potentiometer. The position of the
wiper within the array is determined by the wiper counter.
Up/Down (U/D)
The U/D input controls the direction of the wiper movement and
whether the wiper counter is incriminated or decremented.
Increment (INC)
The INC input is negative-edge triggered. Toggling INC will
move the wiper and either increment or decrement the wiper
counter in the direction indicated by the logic level on the
U/D input.
Chip Select (CS)
The device is selected when the CS input is LOW. The
current wiper counter value is stored in nonvolatile memory
when CS is returned HIGH while the INC input is also HIGH.
