Working Principles

The DS100KR401SQE/NOPB is an analog-to-digital converter that converts continuous analog signals into discrete digital values. It utilizes a sampling technique where the input signal is periodically measured at a high rate. The analog voltage is then quantized into a binary code, representing the digital value.

The ADC employs a successive approximation algorithm to determine the digital output. It compares the input voltage against a reference voltage and iteratively adjusts the approximation until it converges to the closest digital representation.
