Working Principles

The LTC2486IDE#TR is based on the successive approximation register (SAR) architecture. It utilizes an internal reference voltage and a differential input stage to convert analog signals into digital data. The SAR algorithm compares the input voltage with a series of binary-weighted voltages to determine the digital representation. The resulting digital data is then transmitted through the serial interface.
