Analog Devices AD5220 Increment/Decrement Digital Potentiometer Datasheet
The AD5220 is a single-channel, 128-position digitally controlled variable resistor (VR) designed to replace mechanical potentiometers. It features an internal UP/DOWN counter controlled by digital inputs for remote or push-button adjustment without requiring a microcontroller.
Available in 10 kΩ, 50 kΩ, and 100 kΩ end-to-end resistance values, the device operates over an industrial temperature range of -40°C to +85°C. It is offered in SO-8, DIP, and uSOIC packages with very low power consumption (40 pA max) and includes specifications for both rheostat and potentiometer divider modes.
