Working Principle

The principle behind the AD7843ARQZ-REEL is that it converts analog signals into digital data. The A/D converter on the device contains a programmable touch screen controller, which is the first step in the analog-to-digital conversion process. The input signals, in analog form, are digitized into 10-bit or 12-bit resolution (depending on the version of the device). The ADC then samples the input signal and sends out a digital representation of it.

In addition to its ADC, the AD7843ARQZ-REEL also features a programmable, high-resolution microprocessor. This processor is used to program the ADC and to read and process the digital data from the ADC. The microprocessor can also control the gain and filtering of the input signal to optimize accuracy. The microprocessor also provides a wide range of features for controlling the application, such as local digital I/O and analog I/O, programmable timer/interrupt, communication ports and memory.

The AD7843ARQZ-REEL touch screen controller provides an integrated solution for data acquisition applications, offering an excellent balance of features and affordability. With its fast settling time, precision and wide dynamic range, this device offers a great overall value and makes it an ideal choice for many applications.
