Working Principles

The MAX1414EAI+ operates by receiving analog input signals through its input channels. These signals are then conditioned using programmable gain amplifiers (PGAs) to adjust the gain and improve the signal quality. The conditioned signals are then converted into digital format using the built-in 12-bit analog-to-digital converter (ADC). The converted digital data can be accessed through the SPI interface for further processing or analysis.
