DNL Tab
The DNL tab displays a DNL plot for the AD7266 or AD7265.
This plot can be used to examine the dc performance of the
ADC in conjunction with the INL plot. The Linearity Analysis
section contains information on the maximum and minimum
DNL error and the code at which this error occurred.

TAKING SAMPLES
To initiate a conversion and capture the sample data, you must
click the Sample button or the Continuous button. Both the
Sample and the Continuous buttons are located on the top
right-hand corner of the Data Capture tab. When you click the
Sample button, the software instructs the EVAL-CED1Z to take
click the Sample button or the Continuous button. Both the
Sample and the Continuous buttons are located on the top
right-hand corner of the Data Capture tab. When you click the
Sample button, the software instructs the EVAL-CED1Z to take
the required number of samples at the required frequency from
the evaluation board. The AD7266 evaluation board runs with a
sampling speed less than or equal to 2 MSPS, and the AD7265
evaluation board runs with a sampling speed less than 1 MSPS.
You can choose the sampling frequency up to this rate and the
number of samples to be taken.
The samples taken are then uploaded and displayed. An FFT
and/or histogram can be calculated and displayed. If you click
the Continuous button, the software repeats the process
indefinitely until you click Stop. (The Continuous button
switches to Stop when clicked). You can switch between
displaying data from ADC A, ADC B, or both while the
software is running continuously.
