The AD5222 provides a dual channel, 128-posiTIon, digitallycontrolled variable-resistor (VR) device. This device performsthe same electronic adjustment funcTIon as a potenTIometer orvariable resistor. These products were opTImized for instrumentand test equipment push-button applications. Choices betweenbandwidth or power dissipation are available as a result of thewide selection of end-to-end terminal resistance values.
