PRELIMINARY TECHNICAL DATA
AD7466/AD7467/AD7468
APPLICATION HINTS
Grounding and Layout
The printed circuit board that houses the AD7466/67/68
should be designed such that the analog and digital sec-
tions are separated and confined to certain areas of the
board. This facilitates the use of ground planes that can be
separated easily. A minimum etch technique is generally
best for ground planes as it gives the best shielding.
Digital and analog ground planes should be joined at only
one place. If the AD7466/67/68 is in a system where
multiple devices require an AGND to DGND connection,
the connection should still be made at one point only, a
star ground point which should be established as close as
possible to the AD7466/67/68.
Avoid running digital lines under the device as these will
couple noise onto the die. The analog ground plane should
be allowed to run under the AD7466/67/68 to avoid noise
coupling. The power supply lines to the AD7466/67/68
should use as large a trace as possible to provide low im-
pedance paths and reduce the effects of glitches on the
power supply line. Fast switching signals like clocks
should be shielded with digital ground to avoid radiating
noise to other sections of the board, and clock signals
should never be run near the analog inputs. Avoid cross-
over of digital and analog signals. Traces on opposite sides
of the board should run at right angles to each other. This
will reduce the effects of feedthrough through the board. A
microstrip technique is by far the best but is not always
possible with a double-sided board. In this technique, the
component side of the board is dedicated to ground planes
while signals are placed on the solder side.
Good decoupling is also very important. All analog
supplies should be decoupled with 10 F tantalum in
parallel with 0.1 F capacitors to AGND.
All digital
supplies should have a 0.1 F disc ceramic capacitor to
DGND. To achieve the best performance from these
decoupling components, the user should endeavour to keep
the distance between the decoupling capacitor and the VDD
and GND pins to a minimum with short track lenghts
connecting the respective pins.
Evaluating the AD7466/67
Performance
The evaluation board package includes a fully assembled
and tested evaluation board, documentation, and software
for controlling the board from the PC via the EVAL-
BOARD CONTROLLER. The EVAL-BOARD
CONTROLLER can be used in conjunction with the
AD7466/67CB Evaluation board, as well as many other
Analog Devices evaluation boards ending in the CB desig-
nator, to demonstrate/evaluate the ac and dc performance
of the AD7466/67.
The software allows the user to perform ac (fast Fourier
transform) and dc (histogram of codes) tests on the
AD7466/67. See the evaluation board technical note for
more information.
