AD5222 - Increment/Decrement Dual Digital Potentiometer
Analog Devices
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.
