X9221AUSZ

The X9221AUSZ is an integrated, 3-terminal, digital potentiometer that is used in applications where an adjustable voltage or current is required. It is part of a family of similar devices known as Data Acquisition – Digital Potentiometers. The X9221AUSZ can be used to adjust a wide range of resistive components from zero to full scale, including resistors, capacitors, and thermistors.

The X9221AUSZ contains two integrated parts: the control element, which consists of a switch and two resistors, and the data input elements, which consists of three digital inputs for decoding the binary input code. The integrated parts work together to convert the binary input code into an adjustable parameter. The adjustable parameter can then be used to control the output voltage or current of the device.

In the X9221AUSZ, the control element has two series-connected resistors: the potentiometer and the variable resistor. Together, these resistors form a voltage divider circuit, which creates a voltage across the terminals of the device. The potentiometer’s resistance can be adjusted using the digital signals given by the data input elements. This adjustment of the potentiometer resistance changes the voltage divider’s ratio, which in turn changes the voltage across the terminals of the device.

The X9221AUSZ has two different modes of operation: the manual mode and the remote control mode. In manual mode, the user can adjust the potentiometer’s resistance by directly setting the data input elements. In remote control mode, an external voltage or current can be used to control the data input elements, allowing for a greater degree of control over the device’s output voltage or current.

The X9221AUSZ is ideal for applications where a precision adjustable voltage or current is required. It can be used in a wide range of industries, such as automotive, consumer electronics, industrial control, robotics, and medical device design. It is also used in the development and testing of various audio and video equipment, such as audio amplifiers and video monitors.

The X9221AUSZ is a versatile and reliable digital potentiometer that can be used in numerous applications. Its adjustable parameters make it suitable for a range of needs, such as creating adjustable voltage or current sources, or controlling the gain of a signal. It is also highly precision-controlled, making it ideal for accurate testing and measurements.
