Using multi-channel ADC devices to enhance the application performance of high-end data acquisition system
Just as rabbits tempt dogs to race, rabbits must run faster than dogs. The performance of the most stringent data acquisition system is naturally higher than that of civil analog-to-digital converter (ADC). These extremely strict requirements promote the development of IC manufacturers and their users, and there are many innovative methods of “enhancing performance” to […]
How to set an appropriate threshold for the data of a / D conversion interface circuit
