Working Principles

The LTC1296BCSW utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a sample-and-hold circuit to capture the input voltage, which is then compared to a reference voltage using a comparator. The SAR algorithm iteratively determines the most significant bits (MSBs) of the digital output by adjusting the comparator's reference voltage. This process continues until all 12 bits are determined, resulting in a high-resolution digital representation of the input signal.
