Technical details and manufacturing context for ADC/DAC Converter

Definition
A critical electronic component within Data Interface Modules that performs bidirectional signal conversion between analog and digital domains. The ADC (Analog-to-Digital Converter) transforms continuous analog signals from sensors or other analog sources into discrete digital values for processing by digital systems. The DAC (Digital-to-Analog Converter) performs the reverse operation, converting digital data into analog signals for output to actuators, displays, or other analog devices. This component enables communication between analog world interfaces and digital processing systems.
Working Principle
ADC converters sample analog input signals at regular intervals, quantize the amplitude to discrete levels, and encode these levels into binary digital values using techniques such as successive approximation, delta-sigma modulation, or flash conversion. DAC converters reconstruct analog signals from digital input by generating voltage or current outputs corresponding to the digital codes, typically using resistor networks (R-2R ladder) or pulse-width modulation methods.
