Working Principles

The MAX11661AUT+T is an analog-to-digital converter (ADC) that converts analog signals into digital data. It utilizes a 16-bit resolution to provide high accuracy in the conversion process. The device operates by sampling the analog input voltage and converting it into a corresponding digital value.

The ADC employs a successive approximation register (SAR) architecture, which compares the input voltage against a reference voltage. By iteratively adjusting the comparison, the ADC determines the digital representation of the analog signal.

The MAX11661AUT+T communicates with a microcontroller through the Serial Peripheral Interface (SPI). This interface allows for easy configuration and data transfer between the ADC and the microcontroller.
