Data Acquisition is a field which involves collecting and storing data over time. It finds its application in a variety of industries, ranging from medical to manufacturing processes. The data in general is of two types, continuous and discrete. Touch screen controllers are used for data acquisition in the form of touch screens, which act as an interface between the user and the application. The touch screen controller helps in translating the user input from the touch screen into a digital signal, which can be stored and processed further.

The AD7873BRQZ-REEL application field is in the area of data acquisition, as it is a touch screen controller. It is designed for data acquisition through a touch screen, as it can interpret input from the touch screen and convert it to a digital signal. The AD7873BRQZ-REEL touch screen controller operates at 3.3V, making it suitable for most applications. It also has up to 12 channels that can be used to input data from a touch screen. The device features a wide range of features such as variable voltage range, safety features, high accuracy and low power consumption, making it ideal for use in data acquisition applications.

As a touch screen controller, the AD7873BRQZ-REEL works by underlying principles of capacitive sensing. Capacitive sensing is a technology in which two plates are used, placed exactly opposite each other with a distance between them. When a user touches the screen, there is an effect on the capacitance between the two plates. The capacitive changes can then be detected by the device and recognized as input from the user.

The AD7873BRQZ-REel then translates this input into a digital signal which can be stored for further processing. It does this by using its integrated charge transfer circuit, as well as analog filtering, digital signal conditioning, and peak detection. With its on-chip digital-to-analogue converter, the AD7873BRQZ-REEL can take in analogue inputs and convert them to digital output. This is ideal for applications such as touch screens, where the device will need to be able to interpret capacitive input from the user. Additionally, the device has built-in safety features including ESD protection, over- and under-voltage protection, as well as current-sense protection.

The AD7873BRQZ-REEL touch screen controller is suitable for a variety of applications, such as industrial automation and medical equipment. With its wide range of features, it is ideal for data acquisition in touch screen applications, where it can be used to interpret user input from the touch screen and convert it to a digital signal. Additionally, the device has a range of safety features included in the design, making it suitable for applications where safety is paramount.
