Working Principles

ADM237LARZ-REEL operates based on the principle of successive approximation. It converts analog input voltages into digital data by comparing the input voltage with a reference voltage and determining the corresponding digital code.

The conversion process starts when the conversion start input (CONVST) is triggered. The internal circuitry then performs a series of comparisons and adjustments to approximate the input voltage. The resulting digital code is available at the digital output pins (D0-D11) after the conversion is completed.
