ADC1113S125HN-C18 Working Principle

The working principle of the ADC1113S125HN-C18 is based on reconstruction filtering, also known as sigma-delta converters. This means that the device works in a cycle of distinct steps. The ADC1113S125HN-C18 starts by sampling the signal of the analog input at a certain rate. This is done in order to obtain the voltage level of the signal. Then, the format and amplitude of the signal will be compared against the reference voltage. This reference voltage acts as a reference point which will be used in order to decide if the analog input should be converted into a digital signal or not. The comparison phase is followed by a delta conversion phase, where the analog signal is compared to the reference once more. Then, the signal is processed and the output is obtained.

Lastly, the ADC1113S125HN-C18 performs a digital to analog conversion, in order to obtain the analog output. This output will consist of an offset value and a gain value, which are used to modify the voltage and current levels of the signal. The ADC1113S125HN-C18 also features a feedback loop, which is used to continually adjust the voltage of the analog input in order to obtain an accurate digital output. Overall, the working principle of the ADC1113S125HN-C18 is based on the process of sampling signals, comparing them to the reference voltage, and providing an output on a digital format.
