Working Principles

The MAX187ACWE 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 conversions. The input voltage is compared against the internal reference voltage (VREF) and converted into a 12-bit digital value. The conversion process is controlled by the serial interface, allowing easy integration with microcontrollers.
