4-/6-/8-Channel, 16-/14-Bit,
Simultaneous-Sampling ADCs
Spurious-Free Dynamic Range (SFDR)
SFDR is the ratio of the RMS amplitude of the funda-
mental (maximum signal component) to the RMS value
of the next-largest frequency component.
Aperture Delay
Aperture delay (t_AD) is the time delay from the sampling
clock edge to the instant when an actual sample is taken.
Aperture Jitter
Aperture Jitter (t_AJ) is the sample-to-sample variation in
aperture delay.
Channel-to-Channel Isolation
Channel-to-channel isolation indicates how well each
analog input is isolated from the other channels. Channel-
to-channel isolation is measured by applying DC to chan-
nels 1 to 7, while a -0.4dBFS sine wave at 60Hz is applied
to channel 0. A 10ksps FFT is taken for channel 0 and
channel 1. Channel-to-channel isolation is expressed in
dB as the power ratio of the two 60Hz magnitudes.
Small-Signal Bandwidth
A small -20dBFS analog input signal is applied to an
ADC in a manner that ensures that the signal’s slew
rate does not limit the ADC’s performance. The input
frequency is then swept up to the point where the
amplitude of the digitized conversion result has
decreased 3dB.
Full-Power Bandwidth
A large -0.5dBFS analog input signal is applied to an
ADC, and the input frequency is swept up to the point
where the amplitude of the digitized conversion result
has decreased by 3dB. This point is defined as full-
power input bandwidth frequency.
