EVAL-AD5165EBZ:  256-Position, Ultralow Power 1.8 V Logic-Level Digital Potentiometer

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
