Working Principles

The MAX1393ETB+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-speed and accurate conversions. The input analog signal is sampled, quantized, and converted into a binary code representing its amplitude. This digital representation can then be processed by a microcontroller or other digital systems.
