GENERAL OVERVIEW  
The AD5161 provides a compact 3 mm × 4.9 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 a pin selectable SPI  
or I2C compatible digital interface, which can also be used to  
read back the wiper register content. When the SPI mode is  
used, the device can be daisy-chained (SDO to SDI), allowing  
several parts to share the same control lines. In the I2C mode,  
address pin AD0 can be used to place up to two devices on the  
same bus. In this same mode, command bits are available to  
reset the wiper position to midscale or to shut down the device  
into a state of zero power consumption.  
Note:  
The terms digital potentiometer, VR, and RDAC are used interchangeably.  
Purchase of licensed I2C components of Analog Devices or one of its sublicensed  
Associated Companies conveys a license for the purchaser under the Philips I2C  
Patent Rights to use these components in an I2C system, provided that the system  
conforms to the I2C Standard Specification as defined by Philips.  
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.
