NOTES
The AD5260/AD5262 contains 1,968 transistors. Die Size: 89 mil. × 105 mil. 9,345 sq. mil.
1Typicals represent average readings at 25°C and VDD = +5 V, VSS = –5 V.
2Resistor 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. IW = VDD/R for both VDD = +5 V, VSS = –5 V.
3VAB = VDD, Wiper (VW) = No connect.
4INL 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 = 0V. DNL
specification limits of 1 LSB maximum are Guaranteed Monotonic operating conditions.
5Resistor terminals A, B, W have no limitations on polarity with respect to each other.
6Guaranteed by design and not subject to production test.
7Measured at the Ax terminals. All Ax terminals are open-circuit in shutdown mode.
8Worst-case supply current consumed when input all logic-input levels set at 2.4 V, standard characteristic of CMOS logic.
9PDISS is calculated from (IDD ϫ VDD). CMOS logic level inputs result in minimum power dissipation.
10 All dynamic characteristics use VDD = +5 V, VSS = –5 V, VL = +5 V.
11 Measured at a VW pin where an adjacent VW pin is making a full-scale voltage change.
12 See timing diagram for location of measured values. All input control voltages are specified with tR = tF = 2ns (10% to 90% of 3 V) and timed from a voltage level of 1.5 V.
Switching characteristics are measured using VL = 5 V.
13 Propagation delay depends on value of VDD, RL, and CL.
Specifications subject to change without notice.

NOTES
1Stresses above those listed under Absolute Maximum Ratings may cause permanent
damage to the device. This is a stress rating only; functional operation of the device
at these or any other conditions above those listed in the operational sections of this
specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability.
