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.
| Type | Functional Characteristics | Application Examples |
|---|---|---|
| Successive Approximation ADC | Medium-speed, high accuracy, moderate power consumption | Industrial control systems, precision measurement |
| Integrating ADC | High noise rejection, low speed, excellent linearity | Digital multimeters, weigh scales |
| Pipeline ADC | High-speed operation with moderate resolution | Wireless communication base stations, video processing |
| Delta-Sigma ( ) ADC | High resolution, low noise, oversampling architecture | Audio processing, precision sensor interfaces |
| Flash ADC | Extremely high-speed conversion, limited resolution | Radar systems, high-speed oscilloscopes |
Typical ADC architecture includes: - Sample-and-Hold Circuit: Captures and stabilizes input signal - Quantizer: Maps analog values to discrete levels - Encoder: Converts quantized values to binary code - Reference Voltage Circuit: Provides stable voltage Modern ADCs integrate additional components like programmable gain amplifiers and digital filters. Fabricated using CMOS or BiCMOS processes, they come in packages like QFP, TSSOP, and BGA with pin counts ranging from 8 to 256.
