Working Principles

The LTC1274ISW#TRPBF is a high-speed, low-power 12-bit ADC. It utilizes the successive approximation technique to convert analog signals into digital data. The analog input voltage is compared to a reference voltage, and the converter determines the digital representation by successively approximating the input voltage.

The ADC operates using a serial interface, where the input data is provided through the SDI pin and clocked in using the SCK pin. The converted digital data is then available at the SDO pin. The EOC pin indicates the end of the conversion process.
