1N5235B-T Analog to Digital Converters (ADC) highlighting the core functional technology articles and application development cases of Analog to Digital Converters (ADC) that are effective.
Overview of Analog to Digital Converters (ADC)1. Sampling ADCs convert continuous analog signals into discrete digital values. The sampling rate determines how often the analog signal is measured, which is crucial for accurately capturing the signal's characteristics.2. Quantization After sampling, the ADC quantizes the sampled values into finite levels. The number of bits in the ADC determines the resolution; for example, a 12-bit ADC can represent 4096 discrete levels.3. Encoding The quantized values are then encoded into a binary format that can be processed by digital systems, allowing for further analysis and manipulation.1. Successive Approximation Register (SAR) ADC Balances speed and resolution, making it suitable for applications requiring moderate speed and high accuracy.2. Sigma-Delta ADC Known for high resolution and excellent noise performance, often used in audio and precision measurement applications.3. Flash ADC Provides very high-speed conversion but is limited in resolution due to the large number of comparators required, making it ideal for applications needing rapid data acquisition.4. Pipeline ADC Combines the speed of flash ADCs with the resolution of SAR ADCs, suitable for high-speed applications like video processing. Applications of ADCs1.
