NOTES
1 Typical specifications represent average readings at +25°C and VDD = 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.
3 VAB = VDD, Wiper (VW) = no connect.
4 INL and DNL are measured at VW with the RDAC configured as a potentiometer divider similar to a voltage output D/A converter. VA = VDD and VB = 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 PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
9 All dynamic characteristics use VDD = 5 V.
10 See timing diagram for location of measured values. All input control voltages are specified with tR = tF = 2 ns (10% to 90% of 3 V) and timed from a voltage
level of 1.5 V.

NOTES
1 Maximum terminal current is bounded by the maximum current handling of
the switches, maximum power dissipation of the package, and maximum
applied voltage across any two of the A, B, and W terminals at a given
resistance.
2 Package power dissipation = (TJMAX – TA)/θJA.
Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at these or
any other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
