Working Principles

The ADS1225IRGVT is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture combined with a programmable gain amplifier (PGA) and internal reference voltage. The analog input signal is amplified, digitized, and converted into binary code using the SAR algorithm. The resulting digital data can then be processed by a microcontroller or other digital devices.
