GENERAL DESCRIPTION
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 I2 C-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.
Operating from a 2.7 V to 5.5 V power supply and consuming less than 8 µA allows usage in portable battery-operated applications. Note that the terms digital potentiometer, VR, and RDAC are used interchangeably.
