The AD5220 provides a single channel, 128-position digitally controlled variable resistor device. 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.
