EVAL-AD766XCB/AD767XCB
PRELIMINARY TECHNICAL DATA
TESTING METHODS
Histogram
To perform a histogram test, apply a DC signal to the input. It
is advised to filter the signal to make the DC Source noise com-
patible with that of the ADC. C26 provides this filtering.
AC Testing
To perform an AC test, apply a sinusoidal signal to the
evaluation board. Low distortion, better than 100dB, is required
to allow true evaluation of the part. One possibility is to filter the
input signal from the AC source. There is no suggested
bandpass filter but consideration should be taken in the choice.
Furthermore, when the full-scale input range is more than a few
Vpp, it is recommended that you use the on board amplifier to
amplify the signal, thus preventing the filter from distorting the
input signal.
Please refer to Figures 8,9,10 and 11 to see the screens of the
software.
Software Description
The AD16bit.exe is the software which allows you to analyze
different performance characteristics of the AD766X,
AD767X, AD97X and AD67X 16-bit ADC family. The soft-
ware allows you to test the histogram as well as perform
different AC tests.
Setup Requirements
- Evaluation Control Board 2 (ADSP2189)
- Evaluation Board
- Power Supply (AC 15V/1A source could be bought from
ADI)
- Parallel Port Cable (provided with the evaluation control
board)
- AC Source (low distortion)
- DC Source (low noise)
- Bandpass Filter (value based on your signal frequency, low
distortion)
USE OF EVAL-AD766XCB/AD767XCB AS STAND-
ALONE EVALUATION BOARD
You have the option of using the
EVAL-AD766XCB/AD767XCB as a stand-alone evaluation
board. This method does not require the control board, nor does
it require use of the accompanied software. The digital output
will now be available on P1 (20-pin connector, for use in serial
mode) or P2 (40-pin connector, for use in parallel mode). Cer-
tain modifications have to be made on the board to allow proper
operation of the evaluation board. Refer to Table II to obtain
the jumper positions for stand-alone operation. When in stand-
alone,
could be externally applied or is generated
internally according to Table I.
Please refer to Figure 1 to obtain the data output pins on the
connectors.
Data is updated on the falling edge of BUSY.

SUPPLYING THE BOARD FOR STAND-ALONE USE
SJ1 is the analog supply. Connect VA+ to +5V and AGND to
GND. SJ2 is the digital supply. SJ2 requires the same values as
SJ1, and SJ2 may be connected to SJ1. SJ3 is the supply for the
front end amplifier (U6). Connect +12V to VS+, GND to
AGND, and -12V to VS-.
