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.
