Working Principles
The MAX1414EAI+T is an analog-to-digital converter that converts continuous analog signals into discrete digital data. It utilizes a high-speed sampling technique to capture the input signal and quantizes it into 14-bit binary code. The differential inputs help reject common-mode noise, ensuring accurate conversion.
The device operates by comparing the input voltage with a reference voltage generated on-chip. The analog signal is sampled at a high rate using the internal clock signal (CLK), and the resulting digital output is available on the parallel data lines (D[13:0]). The conversion process is controlled by the chip select (CS) signal.
