AD5242 Overview
AD5242 Functional Block Diagram The AD5241/AD52421 provide a single-/dual-channel, 256-position, digitally controlled variable resistor (VR) device. These devices perform the same electronic adjustment function as a potentiometer, trimmer, or variable resistor. Each VR offers a pletely programmable value of resistance between the A terminal and the wiper, or the B terminal and the wiper.
