Working Principles

The LTC2204IUK#PBF operates based on the successive approximation register (SAR) architecture. It samples the analog input signal and compares it to a reference voltage using a comparator. The SAR algorithm then determines the digital representation of the analog signal by successively approximating the input voltage. This process is repeated for each sample, resulting in a stream of digital data.
