Working Principles

The MAX1177AEUP+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 compared to a reference voltage, and the converter determines the digital code that best represents the input voltage.

The ADC operates by sequentially comparing the input voltage with a series of binary-weighted voltages generated internally. The comparison process continues until the digital output code accurately represents the input voltage within the specified resolution.
