Addressable Digital Potentiometer  
General Description  
Features  
The DS1805 addressable digital potentiometer contains  
a single 256-position digitally controlled potentiometer.  
Device control is achieved through a 2-wire serial inter-  
face. Device addressing is provided through three  
address inputs that allow up to eight devices on a sin-  
gle 2-wire bus. The exact wiper position of the poten-  
tiometer can be written or read. The DS1805 is  
available in 16-pin SO and 14-pin TSSOP packages.  
The device is available in three standard resistance val-  
ues: 10kΩ, 50kΩ, and 100kΩ. The DS1805 is specified  
over the industrial temperature range. The DS1805  
provides a low-cost alternative for designs based on  
the DS1803, but require only a single potentiometer.  
♦ 3V or 5V Operation
