GENERAL DESCRIPTION  
The AD5162 provides a compact 3 mm × 4.9 mm packaged  
solution for dual, 256-position adjustment applications. This  
device performs the same electronic adjustment function as a  
3-terminal mechanical potentiometer. Available in four end-to-  
end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), this low  
temperature coefficient device is ideal for high accuracy and  
stability-variable resistance adjustments. The wiper settings are  
controllable through an SPI digital interface. The resistance  
between the wiper and either endpoint of the fixed resistor  
varies linearly with respect to the digital code transferred into  
the RDAC latch.1  
Operating from a 2.7 V to 5.5 V power supply and consuming  
less than 6 µA allows the AD5162 to be used in portable battery-  
operated applications.  
For applications that program the AD5162 at the factory,  
Analog Devices offers device programming software running  
on Windows® NT/2000/XP operating systems. This software  
effectively replaces the need for external SPI controllers, which  
in turn enhances the time to market of systems. An AD5162  
evaluation kit and software are available. The kit includes a  
cable and instruction manual.  
1 The terms digital potentiometer, VR, and RDAC are used interchangeably.
