The working principle of the ADC11DS105CISQ/NOPB is based on the successive approximation technique. The circuit is made up of an analog-to-digital converter (ADC) and a digital-to-analog converter (DAC) connected in a feedback loop. An input voltage is applied to the ADC and the digital output is compared to the analog input. The DAC is then used to generate an output voltage that is compared to the input voltage. The error is then used to generate a corrected digital output. This process is repeated until the error is minimized. The output is then converted back to an analog signal and the process is repeated until the error is minimized.

The ADC11DS105CISQ/NOPB is a versatile ADC that provides high performance and accuracy in a small package. Its low power dissipation makes it ideal for use in low-power applications, and its compatibility with 3.3V and 5V logic levels makes it suitable for use in a variety of applications. Its wide range of input voltage range allows it to be used for data acquisition in various fields. Its internal reference and low differential non-linearity make it an attractive option for high-precision applications. Finally, its successive approximation working principle enables it to convert analog inputs into digital outputs quickly and accurately.
