Working Principle

As a sigma delta ADC, the ADS1217 works by directly sampling analog signals and converting them into digital values. This type of converter functions through a cyclic process of amplification, quantization, and noise shaping. Firstly, the input signal is amplified to a greater dynamic range, and then the signal is compressed through quantization in order to create a digital output without any noise. This process is then repeated in a cyclic fashion until the desired accuracy is achieved. Additionally, noise-shaping is used to remove any outlier input signals.
