GENERAL DESCRIPTION AD5243BRMZ100-RL7

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. The wiper settings are controllable

through the I2

C-compatible digital interface.
