Working Principle

The AD5112BCPZ5-1-RL7 digital potentiometer works by combining a two-wire serial interface with an internal EEPROM to store programmed resistance settings. The EEPROM supports up to seven write cycles, allowing changes to be made quickly and easily. The serial interface supports 10-bit commands and provides a write-protect signal and a command latch input.

The digital potentiometer chip can be programmed to control resistance in a single range, or multiple ranges, depending on the application. It can also be programmed with a resistive divider that produces a ratiometric output. That output is proportionally related to the programmed resistance and can be used directly for many applications. In addition, it can also be used with external components making it versatile enough to meet a wide range of applications.

The AD5112BCPZ5-1-RL7 digital potentiometer is a low-voltage, precisely programmable device that offers many advantages over its mechanical counterparts. With its accurate and flexible programming interface and its ability to store programmed settings in its internal EEPROM, it is ideal for a variety of applications. The device is suitable for use in autocalibration systems and other high precision applications where control, adjustment and compensation are required.
