Note 10: Signal-to-noise-ratio (SNR) is measured both with the other channel idling and converting an out-of-phase signal.
Note 11: Harmonic distortion components two through five are included in the total harmonic distortion specification.
Note 12: Both I and Q inputs are effectively tied together (e.g. driven by power splitter). Signal amplitude is -0.5dB FS at an input
Note 13: Measured with a differential probe, 1pF capacitance.

NL and DNL is measured using a sine-histogram method.
Input offset is the voltage required to cause a transition between codes 0 and -1.
Numbers provided are for DC-coupled case. The user has the choice of AC-coupling, in which case, the DC input
voltage level does not matter.
The peak-to-peak input voltage required, causing a full-scale digitized output when using a trigonometric curve-fitting
algorithm (e.g. FFT).
Guaranteed by design and characterization.
Common-mode rejection ratio is defined as the ratio of the change in the offset voltage to the change in the common-
mode voltage expressed in dB.
Measured with analog power supplies tied to the same potential.
Effective number of bits (ENOB) is computed from a curve-fit referenced to the theoretical full-scale range.
The clock and input frequencies are chosen so that there are 2041 cycles in an 8,192-long record.
The worst case number is presented. Harmonic distortion components two through five are excluded from the noise.
