Data Acquisition - Analog to Digital Converters (ADC)

1. Overview

Analog-to-Digital Converters (ADCs) are semiconductor devices that convert continuous analog signals into discrete digital values. This core functionality enables digital systems to process real-world signals such as temperature, pressure, audio, and sensor data. ADCs are fundamental components in modern electronics, serving critical roles in communication systems, medical equipment, industrial automation, and consumer electronics. Their performance directly impacts system accuracy, speed, and overall efficiency.
