Working Principles

The ICL7107CM44Z operates on the principle of successive approximation. It converts analog signals into digital data by comparing the input voltage with a reference voltage and generating a binary code that represents the analog value.

The internal circuitry of the IC includes a voltage reference, a comparator, a successive approximation register (SAR), and a digital display driver. The analog input voltage is continuously compared with the reference voltage using the SAR, which adjusts its output based on the comparison result. The resulting digital code is then displayed on the output pins.
