Working Principles

The AD7715ARUZ-3REEL7 is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a sigma-delta conversion technique to achieve high resolution. The analog input voltage is compared to a reference voltage, and the resulting difference is quantized and converted into a digital representation.

The device operates by oversampling the analog input at a high frequency and using a digital filter to remove unwanted noise. The filtered signal is then decimated to obtain the final digital output. The serial interface allows the transfer of data between the ADC and a microcontroller or other digital devices.
