Overview
The AD5203AR100-REEL, produced by Analog Devices Inc., is a quad-channel, 64-position digitally-controlled variable resistor (VR) device. This component performs the same electronic adjustment function as a potentiometer or variable resistor, making it ideal for applications requiring precise and programmable resistance adjustments. The device is available in a 24-lead SOIC and TSSOP-24 packages, each containing four independent variable resistors.
