GENERAL OVERVIEW  
The AD5245 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 I2C compatible  
digital interface, which can also be used to read back the wiper  
register content. AD0 can be used to place up to two devices on  
the same bus. 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.
