Working Principles

The ADS1100A0IDBVTG4 is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog voltage is sampled, amplified, and then compared to a reference voltage. The SAR iteratively approximates the input voltage by adjusting the digital code until it matches the analog input within the desired resolution. The resulting digital output represents the converted value of the analog input.
