DS1859E-020

Digital potentiometers, or digipots, are variable resistors that contains a digital controller. The DS1859E-020 is a programmable digipot which is used in various applications, including human–machine interfaces, motor positioning, remote sensing and control systems, and other industrial applications. This digipot device has a few key features that make it a great choice for such applications.

The DS1859E-020 has a maximum resistance of 2 kilohm, and it can be adjusted from 0 kilohm to 2 kilohm in 256 increment steps. Its adjustable range is excellent for controlling analog devices, such as motors, or for adjusting the amount of current going to different components. Additionally, the digipot includes a non-volatile memory, so the setting can be stored and recalled with the device. This is a great feature for applications where the resistance needs to be re-adjusted frequently.

The working principle of the DS1859E-020 is quite simple. The digipot contains an EEPROM (electrically erasable programmable read-only memory), a microcontroller that functions as a digital-to-analog converter, and an adjustable resistor. When power is applied to the device, the microcontroller reads the EEPROM and sets the resistance accordingly. This allows the resistance to be adjusted remotely using just a few lines of code.

In addition, the digipot is also able to sense the resistance of the adjustable resistor and can detect when a connection is opened or closed. This is very useful in applications where the connection status needs to be monitored for safety reasons. Moreover, the device includes an on-board temperature sensor that can be used to measure and control temperature. The sensor can be used to adjust the resistance accordingly, which is especially useful in temperature-sensitive applications.

Overall, the DS1859E-020 is a great choice for a variety of industrial applications. Its adjustable range, non-volatile memory, on-board temperature sensor, and status monitoring capabilities make it an ideal choice for many applications. Furthermore, its simple working principle makes it easy to integrate into any system, making it an ideal solution for many different applications.
