Data acquisition is a term used to describe the process of collecting raw data from a range of physical sources, such as sensors and transducers, other types of transducers, and even direct user input. Increasingly, this data is digitized and stored in computer memory, ready for processing and analysis. Touch screen controllers, like the ADS7846E/2K5G4, are an essential tool in data acquisition, as they enable users to interact directly with the system. In this article, we will explain the application field and working principle of the ADS7846E/2K5G4.

Application Field of the ADS7846E/2K5G4

The ADS7846E/2K5G4 is ideal for use in industrial and medical data acquisition systems, particularly those which require direct user input. The controller is designed to be used with a variety of touch screen displays, and is often used in applications such as patient monitoring, process control, and machine diagnostics. The device also features an automatic calibration system, meaning that it can be easily integrated into existing systems.

Working Principle of the ADS7846E/2K5G4

The ADS7846E/2K5G4 is an incredibly complex device, but the working principle of the controller is relatively straightforward.
