Working Principles

The MAX1142AEAP+ is an analog-to-digital converter that converts continuous analog signals into digital data. It utilizes a successive approximation register (SAR) architecture to achieve high-resolution conversion. The input analog voltage is sampled, quantized, and converted into a digital representation using an internal reference voltage. The converted digital data can then be processed and utilized by a microcontroller or other digital systems.
