Timing Definitions
Aperture Delay: Aperture delay is the time delay between
the external sample command (the rising edge of the clock)
and the time at which the signal is actually sampled. This
delay is due to internal clock path propagation delays.
Aperture Jitter: This is the RMS variation in the aperture
delay due to variation of internal clock path delays.
Data Latency
After the analog sample is taken, the data on the bus is
output at the next rising edge of the clock. This is due to the
output latch of the converter. This delay is specified as the
data latency. After the data latency time, the data
representing each succeeding sample is output at the
following clock pulse. The digital data lags the analog input
by 1 cycle.
Static Performance Definitions
Offset Error and Full-Scale Error use a measured value of
the external voltage reference to determine the ideal plus
and minus full-scale values. The results are all displayed in
LSBs.

Bottom Offset Voltage (V
The first code transition should occur at a level 0.5 LSB
above the negative full-scale. Bottom offset voltage is
defined as the deviation of the actual code transition from
this point.
Top Offset Voltage (V
The last code transition should occur for a analog input that
is 1.5 LSBs below positive full-scale. Top Offset Voltage is
defined as the deviation of the actual code transition from
this point.
Differential Linearity Error (DNL)
DNL is the worst case deviation of a code width from the
ideal value of 1 LSB. The converter is guaranteed to have no
missing codes.
Integral Linearity Error (INL)
INL is the worst case deviation of a code center from a best
fit straight line calculated from the measured data.
