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.
Signal-to-noise-ratio (SNR) is measured both with the other channel idling and converting an out-of-phase signal.
The worst case number is presented. Harmonic distortion components two through five are excluded from the noise.
Harmonic distortion components two through five are included in the total harmonic distortion specification.
Both I and Q inputs are effectively tied together (e.g. driven by power splitter). Signal amplitude is -0.5dB FS at an input
frequency of f
IN
= 200.0180 MHz.
Measured with a differential probe, 1pF capacitance.
