AD5165BUJZ100-R7 (ANALOG DEVICES)

The AD5165BUJZ100-R7 is an ultralow power Digital Potentiometer performs 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 to 5.5V, but its logic voltage requirement is 1.8V 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.
