Preliminary Technical Data
The following details the operation of the C:\Program
Files\Analog Devices\Hi-res ADC’s x.x\ADC.exe software.

2. The part to be evaluated is selected here.
3. The controls are used to set:
Sampling Frequency – Slect the up/donw arrows or enter a
value (which will be rounded).
capture board or local to the evaluation board.
Cnv Mode – This selects between continuous (Cont.) or Burst
conversion modes. In continuous mode, the ADC is
continuously converting. In Burst mode, the ADC is not
converting (sample clock held in inactive state) and the
conversions begin once the “Single Capture” or “Continuous
Capture” buttons have been selected.
Interface mode – This selects the digital interface to the on-
board FPGA.
Byteswap – A subset of the digital interface mode, this is used
to demonstrate byte-wide transfers to the FPGA.

Coding – Another subset to the digital interface mode, this can
be used to select straight binary or 2’s complement output.
Power – This can be used to power down the ADC, power
down the internal reference, etc.
Mode – This selects the conversion mode of operation.
Test – Selection between Histogram, AC or Decimated.
K samples – Number of samples (conversions) to capture.
4. These controls are used for sampling, saving, printing, help,
quite, etc. and are also accessed in the File menu.
Sample (F3) – Captures the amount of k samples and display on
the chart
Contionuous (F4) – Continuously sample and update chart.
Save (F5): – Saves the current data displayed in a text file of row
format.
