Offset Error
Analog Bandwidth
The offset error is the difference, given in number of
LSBs, between the ADC's actual average idle
channel output code and the ideal average idle
channel output code. This quantity is often mapped
into mV.
The analog input frequency at which the power of the
fundamental is reduced by 3 dB with respect to the
low frequency value.
Aperture Delay
Temperature Drift
The delay in time between the falling edge of the
input sampling clock and the actual time at which the
sampling occurs.
The temperature drift coefficient (with respect to gain
error and offset error) specifies the change per
degree Celsius of the parameter from T
to T
. It
is calculated by dividing the maximum deviation of
the parameter across the T
MIN
to T
MAX
range by the
difference (T
MAX
– T
MIN
).
Signal-to-Noise Ratio (SNR)
Aperture Uncertainty (Jitter)
The sample-to-sample variation in aperture delay.
Clock Pulse Width/Duty Cycle
The duty cycle of a clock signal is the ratio of the
time the clock signal remains at a logic high (clock
pulse width) to the period of the clock signal. Duty
cycle is typically expressed as a percentage. A
perfect differential sine wave clock results in a 50%
duty cycle.
SNR is the ratio of the power of the fundamental (P
S
)
to the noise floor power (P
), excluding the power at
dc and the first eight harmonics.
Maximum Conversion Rate
SNR is either given in units of dBc (dB to carrier)
when the absolute power of the fundamental is used
as the reference or dBFS (dB to Full-Scale) when the
power of the fundamental is extrapolated to the
converter's full-scale range.
The maximum sampling rate at which certified
operation is given. All parametric testing is performed
at this sampling rate unless otherwise noted.
Minimum Conversion Rate
Signal-to-Noise and Distortion (SINAD)
The minimum sampling rate at which the ADC
functions.
SINAD is the ratio of the power of the fundamental
(P
S
)
to
the
power
of
components including noise (P
N
) and distortion (P
D
),
but excluding dc.

spectral
Differential Nonlinearity (DNL)
An ideal ADC exhibits code transitions at analog
input values spaced exactly 1 LSB apart. The DNL is
the deviation of any single step from this ideal value,
measured in units of LSBs.
Integral Nonlinearity (INL)
SINAD is either given in units of dBc (dB to carrier)
when the absolute power of the fundamental is used
as the reference or dBFS (dB to full-scale) when the
power of the fundamental is extrapolated to the
converter's full-scale range.
The INL is the deviation of the ADC's transfer
function from a best fit line determined by a least
squares curve fit of that transfer function, measured
in units of LSBs.
Effective Number of Bits (ENOB)
Gain Error
The
performance as compared to the theoretical limit
based on quantization noise.
ENOB
is
a
measure
of
a
converter's
The gain error is the deviation of the ADC's actual
input full-scale range from its ideal value. The gain
error is given as a percentage of the ideal input
full-scale range. Gain error does not account for
variations in the internal reference voltages (see the
Electrical Specifications
section for limits on the
variation of V
REFP
and V
REFM
).
