Working Principles

The MAX1421ECM+D is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a 16-bit resolution to provide a high level of detail in the converted data. The device operates by sampling the analog input voltage at a specified rate and converting it into a binary representation.

The ADC employs a successive approximation algorithm to determine the digital output value. It compares the sampled voltage with a reference voltage and iteratively adjusts the digital code until the difference between the two voltages is minimized. This process continues until the desired accuracy is achieved.
