GENERAL OVERVIEW  
Figure 2.  
The AD5160 provides a compact 2.9 mm × 3 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 wiper settings are controllable through an SPI compatible  
digital interface. The resistance between the wiper and either  
end point of the fixed resistor varies linearly with respect to the  
digital code transferred into the RDAC latch.  
Operating from a 2.7 V to 5.5 V power supply and consuming  
less than 5 µA allows for usage in portable battery-operated  
applications.  
Note:  
The terms digital potentiometer, VR, and RDAC are used interchangeably.
