Signal Chain Designer: ADC Driving

0001-01-01

Signal Chain Designer tells you whether the circuitry in front of your ADC can drive it so the ADC performs to its specifications. This video shows you how. It also shows you how to go to the ADC Driver tool for more information.

ADCs have a sampling capacitor that must be charged every sampling cycle. This capacitor supplies a burst of charge at the input that disturbs the input voltage. This voltage must be settled back to down to 1/2 LSB accuracy when the ADC disconnects the sampling capacitor from the input. Otherwise you will see errors in your signal. This video shows you how to make sure you have a strong enough driver to make sure the signal is settled soon enough for maximum accuracy.
