The AD5241BRZ100 is a single-channel digitally-controlled Variable Resistor performs the same electronic adjustment function as a potentiometer, trimmer or variable resistor. Each VR offers a completely programmable value of resistance between the A terminal and the wiper or the B terminal and the wiper. Wiper position programming defaults to midscale at system power on. When powered, the VR wiper position is programmed by an I²C-compatible, 2-wire serial data interface. It has two extra programmable logic outputs available that enable users to drive digital loads, logic gates, LED drivers and analogue switches in their system.
