The AD7873ARUZ-REEL is a touch screen controller that is specifically designed for data acquisition applications. It is a member of the AD78xx family of devices, which are known for their high performance and accuracy. The AD7873ARUZ-REEL utilizes a 12-bit SAR (Successive Approximation Register) conversion technique to produce a high resolution output signal.

The AD7873ARUZ-REEL has two key features that make it an ideal device for data acquisition applications. The first is the highly accurate, 12-bit SAR architecture. This provides a high degree of signal-to-noise ratio, as well as a wide dynamic signal range. The second key feature is the device’s ability to automatically detect the presence of a touch on the touch sensor and generate the necessary control signals. This eliminates the need for external control logic and makes the design of the application much simpler.

The AD7873ARUZ-REEL works in conjunction with a touch sensor to provide an analog signal that is proportional to the position of the finger on the touch sensor. The device consists of a 12-bit analog-to-digital (A/D) converter, an internal oscillator, and an auxiliary block that provides the necessary control signals. The A/D converter uses the internal oscillator to accrue data from the touch sensor, and then converts it into a digital signal that is proportional to the touch position. This digital signal is then sent to the processor for further processing.

The device also has three auxiliary blocks that provide the necessary control signals for various touch conditions. The first block is the Touch Enable Block (TEB) which is responsible for detecting a touch and generating the enable signal. The second block is the Detection Enable Block (DEB) which is responsible for detecting the presence of a touch and generating the detection signal. The third block is the Detection Time-Out Block (DTB) which is responsible for detecting a touch and generating the time-out signal. All three of these blocks work in conjunction to detect a touch and generate the necessary control signals.

The AD7873ARUZ-REEL is an ideal device for data acquisition applications because of its high performance, accuracy, and its ability to automatically detect the presence of a touch on the touch sensor. The device’s SAR architecture also provides a high degree of signal-to-noise ratio, as well as a wide dynamic signal range. The device’s ability to generate the necessary control signals without requiring external control logic also makes it an attractive option for many data acquisition applications.
