Working Principles

The LTC1323CS16#TRPBF operates based on the successive approximation register (SAR) architecture. It converts analog signals into digital data by comparing the input voltage with a series of binary-weighted voltages generated internally. The SAR algorithm successively approximates the input voltage until the digital representation is obtained.

The device utilizes a differential input configuration, which improves noise rejection and common-mode rejection ratio (CMRR). This ensures accurate and reliable conversion results even in noisy environments.

The built-in reference voltage and temperature sensor contribute to the overall performance of the ADC. The internal reference voltage provides a stable and accurate voltage reference for the conversion process. Additionally, the temperature sensor output allows compensation for variations in the ADC's performance due to temperature changes.
