Working Principles

The MCP3202T-CI/ST operates by sampling an analog signal and converting it into a digital representation using its internal circuitry. The analog signal is compared against a reference voltage (VREF) to determine the digital value. This conversion process is performed simultaneously on both channels, allowing for dual-channel operation.

The ADC utilizes the SPI interface to communicate with a microcontroller or other digital devices. The clock input (CLK) synchronizes the data transfer, while the chip select input (CS) enables the ADC for communication. The converted digital data is then transmitted through the digital output pin (DOUT).
