TERMINOLOGY
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
10-bit resolution indicates that all 1024 codes 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 AD9937 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

where
N
is the bit resolution of the ADC. For the AD9937, 1 LSB
is 1.95 mV.
Power Supply Rejection (PSR)
The PSR is measured with a step change applied to the supply
pins. This represents a very high frequency disturbance on the
AD9937
s power supply. The PSR specification is calculated
from the change in the data outputs for a given step change in
the supply voltage.
