Working Principles

The AS3649-ZWLM is an analog-to-digital converter (ADC) that converts continuous analog signals into discrete digital values. It operates based on the successive approximation method, where it compares the input voltage against a reference voltage and determines the closest digital representation.

The ADC utilizes an internal clock to sample the analog input at a high rate of 1 MSPS. The sampled voltage is then quantized into a 12-bit digital value using a built-in analog-to-digital conversion algorithm. The digital output is provided through a serial interface, making it compatible with various digital systems.
