Working Principles

The MAX128BCAI is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a 12-bit resolution to provide a high level of detail in the converted signal. The device operates by sampling the analog input voltage at a specified rate and converting it into a binary representation.

The ADC employs an internal reference voltage to establish the conversion range. The input voltage is compared to this reference, and the resulting digital value is outputted through a serial interface. The MAX128BCAI can be controlled using control pins such as CS (Chip Select), RD (Read), and WR (Write).
