Working Principles

The AD7710AN operates on the principle of successive approximation. It uses an internal reference voltage and a programmable gain amplifier to convert analog signals into digital data. The analog input is sampled, amplified, and then compared to a series of reference voltages. The converter iteratively adjusts the comparison voltage until it matches the input signal, resulting in a digital representation of the analog input.
