GENERAL OVERVIEW

The AD5243 & AD5248 provide a compact 3x4.9mm packaged

solution for dual 256 position adjustment applications. These

devices perform the same electronic adjustment function as a 3-

terminal mechanical potentiometer (AD5243) or a 2-terminal

variable resistor (AD5248). Available in four different end-to-

end resistance values (2.5k, 10k, 50k, 100k ) these low

temperature coefficient devices are ideal for high accuracy and

stability variable resistance adjustments. The wiper settings are

controllable through the I²C compatible digital interface. The

AD5248 has extra package address decode pins AD0 & AD1

allowing multiple parts to share the same I²C 2-wire bus on a

PCB.

Note:

The terms digital potentiometer, VR, and RDAC are used interchangeably.

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 latch¹.
