GENERAL DESCRIPTIONThe AD5260/AD5262 provide a single- or dual-channel, 256-
position, digitally controlled variable resistor (VR) device.* These
devices perform the same electronic adjustment function as a
potentiometer or variable resistor. Each channel of the AD5260/
AD5262 contains a fixed resistor with a wiper contact that taps the
fixed resistor value at a point determined by a digital code loaded
into the SPI-compatible serial-input register. The resistance between
the wiper and either end point of the fixed resistor varies linearly
with respect to the digital code transferred into the VR latch. The
variable resistor offers a completely programmable value of resistance,
between the A terminal and the wiper or the B terminal and the wiper.
The fixed A to B terminal resistance of 20kW, 50kW, or 200kW has
a nominal temperature coefficient of 35 ppm/∞C. Unlike the majority
of the digital potentiometers in the market, these devices can operate
up to 15 V or ±5 V provided proper supply voltages are furnished.
Each VR has its own VR latch, which holds its programmed resistance
value. These VR latches are updated from an internal serial-to-parallel
shift register, which is loaded from a standard 3-wire serial-input
digital interface. The AD5260 contains an 8-bit serial register
while the AD5262 contains a 9-bit serial register. Each bit is clocked
into the register on the positive edge of the CLK. The AD5262
address bit determines the corresponding VR latch to be loaded
with the last 8 bits of the data word during the positive edging of
CS strobe. A serial data output pin at the opposite end of the serial
register enables simple daisy chaining in multiple VR applications
without additional external decoding logic.An optional reset pin
(PR) forces the wiper to the mid-scale position by loading 80H into
the VR latch.
*The terms digital potentiometers, VR, and RDAC are used interchangeably.

The AD5260/AD5262 are available in thin surface-mount TSSOP-14
and TSSOP-16 packages. All parts are guaranteed to operate over
the extended industrial temperature range of –40∞C to +85∞C.
AD5260/AD5262–SPECIFICATIONS
(VDD = +15 V, VSS = 0 V or, VDD = +5 V, VSS = –5 V, VL = +5 V, VA = +5 V,
VB = 0 V, –40�C < TA < +85�C unless otherwise noted.)

AD5260/AD5262NOTES
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=–5V.
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 � VDD). CMOS logic level inputs result in minimum power dissipation.All dynamic characteristics use VDD = +5 V, VSS = –5 V, VL = +5 V.Measured at a VW pin where an adjacent VW pin is making a full-scale voltage change.See timing diagram for location of measured values. All input control voltages are specified with tR=tF=2ns(10% to 90% of 3V) and timed from a voltage level of 1.5V.
Switching characteristics are measured using VL = 5 V.Propagation delay depends on value of VDD, RL, and CL.

NOTESStresses 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.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 setting.Package Power Dissipation = (TJ MAX – TA)/ θJA

CAUTIONESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000V readily
accumulate on the human body and test equipment and can discharge without detection. Although
the AD5260/AD5262 features proprietary ESD protection circuitry, permanent damage may occur
on devices subjected to high-energy electrostatic discharges. Therefore, proper ESD precautions
are recommended to avoid performance degradation or loss of functionality.
