Data acquisition is a key element in every sector of today’s engineering industries. This process involves collecting and storing digital data from physical objects and systems. Digital potentiometers are important components for the digital data acquisition systems. The X9015UM8IZT1 is a digital potentiometer which provides various advantages in different application fields. This article will discuss the application fields and working principle of the X9015UM8IZT1.

Description

The X9015UM8IZT1 is a complete monolithic voltage controlled resistance element which supports six different wiper regions and provides a low resistance path between them. The device also offers excellent linearity and temperature stability. It features a typical absolute max operating voltage limit of 2.25V and requires low operating current. The equivalent circuit of the X9015UM8IZT1 is shown in the figure.

Equivalent Circuit of the X9015UM8IZT1

Application Field

The X9015UM8IZT1 digital potentiometer is used in different application fields including:

  • Communication Networks: In communication networks digital potentiometers are used for calibrating the gain, frequency, or power output of receivers, transmitters, and oscillators.
  • GPS: Digital potentiometers are also used in the automatic acquisition and tracking circuits of a GPS receiver.
  • Automotive: Digital potentiometers are used to control and adjust the speed, temperature, voltage, and power of automotive systems.
  • Consumer Electronics: Digital potentiometers are used in consumer electronics like laptops, cameras, and home theater systems to control the gain, brightness, and contrast of a display.
  • Medical: Digital potentiometers are used in medical applications like x-ray systems and medical imagery systems to control the voltage, current, and resistance.

Working Principle

The X9015UM8IZT1 digital potentiometer works according to the linear resistance division principle in which two resistors are connected in series such that their total resistance is given by:

RT = R1 + R2

In the equivalent circuit of the X9015UM8IZT1, the resistor R1 represents the transfer impedance while the resistor R2 is associated with the wiper position that is controlled by the voltage applied to the wiper terminal. The ratio of two resistors is determined by the voltage applied to the wiper terminal and is given by:

R2 / R1 = VW / VDD = VW / VREF - 1

This equation shows that the wiper position is proportional to the voltage applied to the wiper terminal.

The X9015UM8IZT1 digital potentiometer can be operated up to a maximum operating voltage of 2.25V. As the voltage applied to the wiper terminal increases, the resistance or impedance of the device increases as well. This property can be used in different applications where a variable resistance is required. For example, it can be used in variable gain amplifiers, audio circuits, and other sensitive electronics applications.

Conclusion

The X9015UM8IZT1 digital potentiometer is an important component for the digital data acquisition systems. It can be used in various application fields including communication networks, GPS, automotive, consumer electronics, and medical. The device works according to the linear resistance division principle and allows precise control of voltage, current, and resistance. It offers excellent linearity and temperature stability and can be operated up to a maximum operating voltage of 2.25V.
