Working Principles

The TLC542CDWG4 is an 8-bit analog-to-digital converter that converts continuous analog signals into discrete digital data. It operates by sampling the analog input voltage and converting it into a binary representation using its internal circuitry. The conversion process is controlled by the chip select (CS) and clock (CLK) inputs, and the converted digital data is outputted serially through the DOUT pin.
