Power Up and Down Requirements

The recommended power up sequence is to apply VCC/VSS

first, then the potentiometer voltages. During power-up, the

data sheet parameters for the DCP do not fully apply until 1

millisecond after VCC reaches its final value. The VCC ramp

AC Timing

spec is always in effect. In order to prevent unwanted tap

position changes, or an inadvertent store, bring the CS and

INC high before or concurrently with the VCC pin on

powerup.
