Working Principles

The LTC2376HMS-18#PBF utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs an internal reference voltage (VREF) to establish the conversion range. The analog input voltage is compared to a series of binary-weighted voltages generated by the SAR circuitry. The conversion process iteratively determines the most significant bits (MSBs) first, followed by the least significant bits (LSBs). The resulting digital output is then transmitted via the SPI interface.
