GENERAL OVERVIEW

The AD5165 provides a compact 2.9 mm × 2.8 mm packaged
solution for 256-position adjustment applications. These devices
perform the same electronic adjustment function as mechanical
potentiometers or variable resistors, with enhanced resolution,
solid-state reliability, and superior low temperature coefficient
performance. The AD5165’s supply voltage requirement is 2.7 V
to 5.5 V, but its logic voltage requirement is 1.8 V to VDD. The
AD5165 consumes very low quiescent power during standby
mode and is ideal for battery-operated applications.
Wiper settings are controlled through a simple 3-wire interface.
The interface is similar to the SPI® digital interface except for the
inverted chip-select function that minimizes logic power con-
sumption in the idling state. The resistance between the wiper
and either endpoint of the fixed resistor varies linearly with
respect to the digital code transferred into the wiper register.
Operating from a 2.7 V to 5.5 V power supply and consuming
less than 50 nA typical standby power allows use in battery-
operated portable or remote utility device applications.

ELECTRICAL CHARACTERISTICS—100 kΩ VERSION
VDD = 5 V ± 10%, or 3 V ± 10%; VA = VDD; VB = 0 V; –40°C < TA < +125°C; unless otherwise noted.
Table 1.


1 Typical specifications represent average readings at +25°C and VDD = 5 V. 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. 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. Resistor terminals A, B, and W have no limitations on polarity with respect to each other.
6 Guaranteed by design and not subject to production test. PDISS is calculated from (IDD × VDD). CMOS logic level inputs result in minimum power dissipation.
8 All dynamic characteristics use VDD = 5 V.

level of 1.5 V.
ABSOLUTE MAXIMUM RATINGS
TA = +25°C, unless otherwise noted.1, 2
Table 3.

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; 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.
ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on
the human body and test equipment and can discharge without detection. Although this product 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.
