Working Principles

The ADS4122IRGZT is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It achieves this by sampling the analog input at a high speed and quantizing the sampled values into digital codes. The converted digital data can then be processed and analyzed by a digital system.

The ADC operates by using an internal clock to sample the analog input voltage at regular intervals. The sampled voltage is then compared to a reference voltage, and the result is encoded into a binary code. The resolution of the ADC determines the number of bits used to represent the analog signal, with higher resolutions providing more precise digital representations.
