GENERAL DESCRIPTION
The AD5203 provides a quad channel, 64-position digitallycontrolled variable resistor (VR) device. These parts perform the same electronic adjustment function as a potentiometer or variable resistor. The AD5203 contains four independent variable resistors in a 24-lead SOIC and the compact TSSOP-24 packages.
