Increment/Decrement Timing
NOTES:
1. Absolute linearity is utilized to determine actual wiper voltage versus expected voltage = [V(R
W(n)(actual)
)-V(R
W(n)(expected)
)]/MI
V(R
W(n)(expected)
) = n(V(R
H
)-V(R
L
))/255 + V(R
L
), with n from 0 to 255.
2. Relative linearity is a measure of the error in step size between taps = [V(R
W(n+1)
)-(V(R
W(n)
) + MI)]/MI, with n from 0 to 254
3. 1 Ml = Minimum Increment = [V(R

4. Typical values are for T
A
= 25°C and nominal supply voltage.
5. This parameter is not 100% tested.

, with T1 & T2 being 2 temperatures, and n from 0 to
255.
7. Measured with wiper at tap position 255, R
L
grounded, using test circuit.
8. t
WC
is the minimum cycle time to be allowed for any nonvolatile write by the user, unless Acknowledge Polling is used. It is the time from a valid
STOP condition at the end of a write sequence of a 2-wire interface write operation, or from the rising edge of CS of a valid “Store” operation of
the Up/Down interface, to the end of the self-timed internal nonvolatile write cycle.
9. The recommended power up sequence is to apply V
CC
/V
SS
first, then the potentiometer voltages. During power up, the data sheet parameters
for the DCP do not fully apply until t
D
after V
CC
reaches its final value. In order to prevent unwanted tap position changes, or an inadvertant
store, bring the CS pin high before or concurrently with the V
CC
pin on power up.
