Working Principles

The HI7190IP is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It utilizes a successive approximation algorithm to achieve high-resolution conversion. The analog input voltage is sampled at a fast rate determined by the clock input. The internal circuitry then compares the sampled voltage with a reference voltage to determine the digital representation. The converted digital data is available at the output pins for further processing.
