GENERAL DESCRIPTION
The AD5222 provides a dual channel, 128-position, digitally controlled variable-resistor (VR) 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. Choices between bandwidth or power dissipation are available as a result of the wide selection of end-to-end terminal resistance values.
