Working Principles

The LTC2389CUK-18 utilizes a successive approximation register (SAR) architecture for analog-to-digital conversion. It employs a combination of sample-and-hold circuitry, a comparator, and a digital-to-analog converter (DAC) to convert the analog input voltage into a digital representation.

The SAR ADC operates by iteratively comparing the input voltage with a series of reference voltages generated by the internal DAC. The comparator determines whether the input voltage is higher or lower than the reference voltage at each step. This process continues until the most significant bit (MSB) is determined, resulting in an accurate digital representation of the analog input.
