DEFINITIONS OF SPECIFICATIONS
Differential Nonlinearity (DNL)
An ideal ADC exhibits code transitions that are exactly 1 LSB
apart. DNL is the deviation from this ideal value. Thus, every code
must have a finite width. No missing codes guaranteed to 14-bit
resolution indicates that all 16,384 codes, respectively, must
be present over all operating conditions.
Peak Nonlinearity
Peak nonlinearity, a full signal chain specification, refers to the
peak deviation of the output of the AD9824 from a true straight
line. The point used as “zero scale” occurs 1/2 LSB before the
first code transition. “Positive full scale” is defined as a Level 1,
1/2 LSB beyond the last code transition. The deviation is measured
from the middle of each particular output code to the true straight
line. The error is then expressed as a percentage of the 2 V ADC
full-scale signal. The input signal is always appropriately gained up
to fill the ADC’s full-scale range.
Total Output Noise
The rms output noise is measured using histogram techniques.
The standard deviation of the ADC output codes is calculated
in LSB and represents the rms noise level of the total signal
chain at the specified gain setting. The output noise can be
converted to an equivalent voltage using the relationship
1 LSB = (ADC Full Scale/2
N
codes) where N is the bit resolution
of the ADC. For the AD9824, 1 LSB is 125
μ
V.
Power Supply Rejection (PSR)
The PSR is measured with a step change applied to the supply
pins. This represents a high frequency disturbance on the
AD9824’s power supply. The PSR specification is calculated
from the change in the data outputs for a given step change in
the supply voltage.
Internal Delay for SHP/SHD
The internal delay (also called aperture delay) is the time delay
that occurs from when a sampling edge is applied to the AD9824
until the actual sample of the input signal is held. Both SHP and
SHD sample the input signal during the transition from low to
high, so the internal delay is measured from each clock’s rising
edge to the instant the actual internal sample is taken.
