Abstract: This application note demonstrates how to quickly verify the dynamic performance of any analog-to-digital converter (ADC) without requiring expensive data-processing software. Although Microsoft® Excel® limits the number of data points to 4096, this application note shows the successful use of Excel for FFT processing and displaying the results in a typical FFT spectrum.
