Working Principles

The ADS1225IRGVRG4 is an analog-to-digital converter that converts analog signals into digital data. It utilizes a high-resolution sigma-delta architecture to achieve precise measurements. The input analog signal is amplified by the programmable gain amplifier (PGA) and then converted into a digital representation using the internal voltage reference. The converted digital data is then transmitted through the serial interface for further processing.
