GENERAL DESCRIPTION
The AD5235 provides a dual channel, digitally controlled variable resistor (VR) with resolutions of 1024 positions. These devices perform the same electronic adjustment function as a potentiometer or variable resistor. The AD5235’s versatile programming via a Micro Controller allows multiple modes of operation and adjustment.
