Note 11: Effective Number of Bits (ENOB) and Signal-to-Noise Plus Distortion (SINAD) are computed from a curve fit referenced to
Note 12: Total Harmonic Distortion (THD) is computed from the first five harmonics.
Note 13: Guaranteed by design with a reset pulse one clock period long or greater.
Note 14: The DREADY to DATA propagation delay is measured from the 50% point on the rising edge of the DREADY signal (when

the output data changes) to the 50% point on a data output bit. This places the falling edge of the DREADY signal in the
middle of the data output valid window, within the differences between the DREADY and DATA rise and fall times, which
gives maximum setup and hold time for latching external data latches.
