AD5220 Datasheet PDF

●The AD5220BRZ10 is a single-channel increment/decrement Digital Potentiometer for use with line impedance matching. This device performs the same electronic adjustment function as a potentiometer or variable resistor. These products were optimized for instrument and test equipment push-button applications. A choice between bandwidth or power dissipation is available as a result of the wide selection of end-to-end terminal resistance values. The AD5220 contains a fixed resistor with a wiper contact that taps the fixed resistor value at a point determined by a digitally controlled up/down counter. The resistance between the wiper and either end point of the bed resistor provide and a constant resistance step size that is equal to the end-to-end resistance divided by the number of position.

● Increment/decrement count control

● 40µA Maximum very low power

●ESD sensitive device. Electrostatic charges as high as 4000V readily accumulate on the human body and test equipment and can discharge without detection.
