AD5243BRMZ100 General Description

The AD5243 and AD5248 provide a compact 3 mm × 4.9 mmpackaged solution for dual, 256-position adjustment applications.The AD5243 performs the same electronic adjustment functionas a 3-terminal mechanical potentiometer, and the AD5248performs the same adjustment function as a 2-terminal variableresistor. Available in four end-to-end resistance values (2.5 kΩ,10 kΩ, 50 kΩ, and 100 kΩ), these low temperature coefficientdevices are ideal for high accuracy and stability-variableresistance adjustments. The wiper settings are controllablethrough the I²C-compatible digital interface. The AD5248 hasextra package address decode pins, AD0 and AD1, allowingmultiple parts to share the same I²C, 2-wire bus on a PCB. Theresistance between the wiper and either endpoint of the fixedresistor varies linearly with respect to the digital code transferred into the RDAC latch. (The terms digital potentiometer, VR,and RDAC are used interchangeably.)
