Working Principles

The LTC2107IUK utilizes a successive approximation register (SAR) architecture to convert analog signals into digital data. It employs a combination of sample-and-hold, comparator, and digital logic circuits to achieve high-speed and high-resolution conversion.

During operation, the analog input voltage is sampled and held, and then compared to a reference voltage. The comparator generates a digital output based on the comparison result, which is subsequently processed by the internal logic to produce the final digital output.
