The AD5259 (from Analog Devices) offers an ideal solution for most digital potentiometer applications. Learn how to use the AD5259 using our I2C Mini Module and take control of one on-board I2C controlled potentiometer with 256 taps. This version is equipped with a 50K digital Potentiometer (but 5K, 10K, and 100K are also available). The AD5259 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 caution close examination of the datasheet to make sure your application is voltage compatible with the AD5259.
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 AD5259 is strictly limited to 5ma of current through the potentiometer. Voltages through the AD5259 potentiometer should NEVER exceed +5VDC at 5ma.
