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.
