50K Digital Potentiometer 2-Channel

  • Two 50K Digital Potentiometers
  • +5V 5ma Handling per Potentiometer
  • 400 KHz Communication Speed
  • Add up to 4 of these per I2C Port
  • 0x2C I2C Start Address


The AD5252 (from Analog Devices) offers an ideal solution for most digital potentiometer applications. Learn how to use the AD5252 using our I2C Mini Module and take control of 2 on-board I2C controlled potentiometers, each with 256 taps. This version is equipped with 50K digital potentiometers (but 1K, 10K, and 100K are also available). The AD5252 supports wiper read-back, allowing you to easily read the current wiper settings.

Digital potentiometers are an ideal solution to replace many types of mechanical potentiometers, but we advise close examination of the datasheet to make sure your application is voltage compatible with the AD5252.

The AD5254 may also be used in:

  • programmable gain/offset control applications,
  • programmable power supplies,
  • programmable filters,
  • low-resolution digital-to-analog conversion,
  • LED brightness adjustment, and
  • sensor calibration applications.

The AD5252 is strictly limited to 5ma of current through each potentiometer. Voltages through the AD5252 potentiometers should NEVER exceed +5VDC at 5ma.

Mini Modules

Our mini modules provide a standardized footprint to simplify the design of your project, and allow for a smaller form factor without sacrificing the plug-and-play  ease of use that our product line affords.

All I²C Mini Modules are designed to operate at 5VDC. Using a convenient quick connect 4-Pin plug, devices can be daisy-chained onto the I²C Bus, eliminating the need for soldering. Simply plug together the devices you need for your next automation application.

Pull-up resistors are included with all ControlEverything.com master devices. If you are wiring in your own I²C port, on-board 4.7K jumper-selectable pull-up resistors are available for convenience purposes.

All mini modules are 50.8 x 31.75 mm.
