Working Principles

The MAX12900AATJ+T is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog voltage is sampled and held, and then compared to a reference voltage. The SAR algorithm determines the digital representation of the input voltage by iteratively adjusting the comparison value. The resulting digital data is then transmitted via the SPI interface.
