General Description

The AD5243 and AD5248 provide a compact 3 mm × 4.9 mm packaged solution for dual, 256-position adjustment applications.

The AD5243 performs the same electronic adjustment function as a 3-terminal mechanical potentiometer, and the AD5248 performs the same adjustment function as a 2-terminal variable resistor.

Available in four end-to-end resistance values (2.5 kΩ, 10 kΩ, 50 kΩ, and 100 kΩ), these low temperature coefficient devices are ideal for high accuracy and stability-variable resistance adjustments.
