1. What is the working principle of ADCs and DACs?
ADC converts analog signals (such as voltage) into digital signals (such as binary numbers), while DAC performs the opposite operation, converting digital signals into analog signals, typically used in devices that require analog output.
-
2. Which applications require special purpose ADCs and DACs?
Special purpose ADCs/DACs are commonly used in medical devices (such as electrocardiograms), automotive electronics (such as sensor signal processing), industrial automation, audio processing, high-precision measuring instruments, and other fields that require high signal processing.
-
3. How to choose ADC/DAC suitable for specific applications?
When selecting, consideration should be given to the resolution, sampling rate, signal-to-noise ratio, power consumption, number of input/output channels, linearity, operating temperature range, and whether it meets the standards or certification requirements of the target application.
-
4. How does the sampling rate of ADCs affect data acquisition performance?
The sampling rate determines how many times an ADC can read a signal per second. A higher sampling rate is suitable for high-speed signals or precise dynamic signal processing, while a lower sampling rate is suitable for collecting steady-state or slowly changing signals.
