Working Principles

The MAX188BEAP is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a 12-bit resolution to provide accurate measurements. The device operates by sampling the analog input voltage and converting it into a digital representation using its internal ADC core. The converted digital data is then transmitted through the SPI interface for further processing or storage.
