Working Principles

ICL7107RCPLZ utilizes a successive approximation technique to convert analog signals into digital data. It consists of an analog multiplexer, a comparator, a successive approximation register (SAR), and a digital-to-analog converter (DAC). The analog input is sampled and compared with the internal reference voltage using the SAR. The DAC generates a digital output based on the comparison results, which is then displayed on the multiplexed segment outputs.
