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 different  
end-to-end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ),  
this low temperature coefficient device is ideal for high accu-  
racy 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 RDAC1 latch.  
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 any external SPI controllers, which in turn  
enhances users’ systems time-to-market. An AD5162 evaluation  
kit and software are available. The kit includes a cable and  
instruction manual.
