Working Principles

The MAX1187ACUI+ utilizes a successive approximation register (SAR) architecture for analog-to-digital conversion. It samples the input voltage and compares it to a reference voltage, iteratively approximating the digital representation of the analog signal until the desired resolution is achieved.

The ADC's internal circuitry includes a sample-and-hold amplifier, a comparator, a SAR logic block, and a digital interface. The sample-and-hold amplifier captures and holds the input voltage during the conversion process. The comparator compares the sampled voltage with the reference voltage, generating a digital output based on the comparison result. The SAR logic block performs the successive approximation algorithm to determine the digital code corresponding to the input voltage. Finally, the digital interface communicates the converted data to an external microcontroller or processor.
