AD5243EVAL: 256-Position Dual Channel I^2C Compatible Digital Potentiometer

The AD5243 provides a compact 3 mm x 4.9 mm packaged solution for dual 256-position adjustment applications. This device performs the same electronic adjustment function as a 3-terminal mechanical potentiometer or variable resistor.

Available in four different end-to-end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, 100 kΩ), these low temperature coefficient devices are ideal for high accuracy and stability variable resistance adjustments. The wiper settings are controllable through the I^2C compatible digital interface.

The resistance between the wiper and either end point of the fixed resistor varies linearly with respect to the digital code transferred into the RDAC latch.

Operating from a 2.7 to 5.5 volt power supply and consuming less than 5 uA allows for usage in portable battery operated applications. All parts are guaranteed to operate over the extended automotive temperature range of -40°C to +125°C
