Data Acquisition - Digital Potentiometers

AD5235BRU25-EP-RL7 digital potentiometers are used for data acquisition applications. These devices feature a resistive element made of mixed metal oxide that is used to vary an electrical parameter such as resistance or voltage. Digital potentiometers are often seen as a variable adjustment to phase locked loops, voltage controlled oscillators, or a variety of other applications.

Digital potentiometers were specifically designed to be used in data acquisition applications where a controlled amount of resistance is needed to execute a desired behavior or operation. These devices can be programmed via an external control voltage to the terminal or through a microcontroller, allowing the user to adjust their resistance in real-time.

Working Principle of AD5235BRU25-EP-RL7

The working principle of the AD5235BRU25-EP-RL7 digital potentiometer is simple. It is based on a resistive element that varies the electrical parameter in response to programming. This varies the resistance of the device in both the clockwise and anti-clockwise directions.

The AD5235BRU25-EP-RL7 works by allowing a given number of terminations that connect to the wiper contact and the common terminal in order to vary the resistance. Within the device, there are two changes of resistance, in the common terminal and the wiper contact, that are adjusted in response to the programmed voltage. This allows for the adjustment of the resistance to transfer from the common terminal to the wiper contact, which provides the desired value.

By adjusting the physical size of the resistive element, the AD5235BRU25-EP-RL7 can produce a varied response to different electrical signals as well as provide a desired behavior in the application.

Application of AD5235BRU25-EP-RL7

The resistance of the AD5235BRU25-EP-RL7 digital potentiometer can be adjusted via a microcontroller. This makes the device suitable for a variety of data acquisition applications such as in medical or industrial systems, where a varying resistance can be used to transfer information such as temperature, light intensity, or pressure. Other applications of the device include LED dimming, DC motor control, and power supply voltage adjustment.

In addition to providing resistance, the device can also be used as an electronically controlled switch, like in automotive lighting applications. The device switches can be adjusted to various positions, triggering a variety of tasks like flashing the brake lights or turning on the headlights. For these applications, the device can be easily connected to the external switch.

The device can also be used in combination with sensors such as temperature, humidity, and pressure sensors. This can be done by adjusting the resistance of the potentiometer in order to detect the desired position or current parameters. For example, an increase in the resistance can be used to detect an increase in temperature and vice versa. This is one of the main advantages of the device, as it enables measurements to be taken in real-time.

Conclusion

In conclusion, AD5235BRU25-EP-RL7 digital potentiometers are used in a variety of data acquisition applications. The device features a resistive element that can be programmed via an external control voltage to execute a desired behavior or operation. Furthermore, its resistance can be adjusted via a microcontroller, allowing it to be used for a range of applications from digitally controlled switches to temperature detection.
