Typical specifications represent average readings at 25°C and V
DD
= 5 V.
2
Resistor position nonlinearity error R-INL is the deviation from an ideal value measured between the maximum resistance and the minimum resistance wiper
positions. R-DNL measures the relative step change from ideal between successive tap positions. Parts are guaranteed monotonic.

DD
and V
B
= 0 V.
DNL specification limits of ±1 LSB maximum are guaranteed monotonic operating conditions.
5
Resistor terminals A, B, W have no limitations on polarity with respect to each other.
6
Guaranteed by design and not subject to production test.
7
Measured at the A terminal. The A terminal is open circuited in shutdown mode.
8
P
DISS
is calculated from (I
DD
× V
DD
). CMOS logic level inputs result in minimum power dissipation.

10
See timing diagrams for locations of measured values.

The maximum t
HD:DAT
must be met only if the device does not stretch the low period (t
