Data acquisition is a term used to describe the acquisition, recording, organization, analysis, and display of data from a variety of sources. Data acquisition is an important procedure for obtaining information, as well as controlling, measuring, and analyzing it for research and development purposes. Touch screen controllers are one of the latest developments in data acquisition technology, and the AD7873ACPZ-REEL is among the most advanced touch screen controllers available on the market.

AD7873ACPZ-REEL Application Field

The AD7873ACPZ-REEL is an 8-bit microcontroller-based touch screen controller designed for use with resistive touch screens. It offers low power consumption and minimal noise interference. This touch screen controller is suitable for point-of-sale terminals, industrial human-machine interfaces (HMIs), medical equipment, digital game controllers, and other applications in which fast and accurate touch response is needed. It is also compatible with a variety of display technologies, including LCD (liquid crystal display) and DSTN (double-layer super twisted nematic).

How AD7873ACPZ-REEL Works?

The AD7873ACPZ-REEL is based on a proprietary capacitance-sensing system. This technology provides reliable and accurate touch response with minimal power consumption. The system works by measuring the difference in electrical potential between two conductive layers (typically ITO, indium tin oxide) on a resistive touch screen. The system sends out a low-power alternating current (AC) signal, which is measured by a pair of electrodes on the touch screen. When the finger or stylus touches the touch screen, it changes the capacitance of the ITO layers, which is then measured by the system and used to identify the touch point. This system is able to measure the position of up to four separate touches at the same time, and can be used to accurately detect various gestures, such as single touches, swipes, slides, and rotations. The AD7873ACPZ-REEL also comes with a built-in analog-to-digital converter (ADC), which allows the controller to directly digitize raw data from the touch screen. This eliminates the need for a separate ADC, which can be costly and power-hungry. The AD7873ACPZ-REEL is also designed for robustness and long-term stability. It has advanced noise immunity and power supply rejection, which prevents false triggering and delivers reliable performance even in harsh environments. The controller also has programmable performance parameters, so developers can customize its performance to match the application’s requirements.

Conclusion

The AD7873ACPZ-REEL is a high-performance touch controller designed specifically for use with resistive touch screens. It provides reliable and accurate touch response with minimal power consumption, and is suitable for a variety of applications. It has advanced noise immunity and power supply rejection features, as well as programmable performance parameters, providing developers with full control over the device’s performance. As such, the AD7873ACPZ-REEL is an ideal choice for data acquisition applications that require fast and accurate touch response.
