over the "Appertur Uncertainty Jitter)?
2) When you apply an input votage of 3V, what is the "shortest" time needed to
"Track-and-Hold" the input signal?
1) We wouldn't normally characterize aperture uncertainty over temperature but
you can see the effect of it in figure 9 (showing the variation of SINAD and
SNR over temperature). The aperture uncertainty will contribute to the noise.
2) The speed of the analog input stage is characterized by its -3dB bandwidth
of 120MHz. If you have a fast rising signal at the input, then the ADC front
end will behave like an RC single pole low pass filter with cutoff frequency at
120MHz. The time constant is t= 1/2*pi*f = 1.3ns to reach 63% of the final
value. You can calculate the settling time to any given percentage T =
e.g. to 0.1% the settling time is -ln(0.1/100)*1.3ns = 6.9*1.3ns = 9.0ns.
