TERMINOLOGY

Total Output Noise

Differential Nonlinearity (DNL)

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

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.

1LSB = ADC Full Scale 2^Ncodes

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.

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.
