Application

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 consumption 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.
