AD7450A/AD7440
APPLICATION HINTS
Grounding and Layout
The printed circuit board that houses the AD7450A/
AD7440 should be designed so that the analog and digital
sections are separated and confined to certain areas of the
board. This facilitates the use of ground planes that can
be easily separated. A minimum etch technique is gener-
ally best for ground planes as it gives the best shielding.
Digital and analog ground planes should be joined in only
one place and the connection should be a star ground
point established as close to the GND pin on the
AD7450A/AD7440 as possible. Avoid running digital
lines under the device as this will couple noise onto the
die. The analog ground plane should be allowed to run
under the AD7450A/AD7440 to avoid noise coupling.
The power supply lines to the AD7450A/AD7440 should
use as large a trace as possible to provide low impedance
paths and reduce the effects of glitches on the power sup-
ply 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 run near the
analog inputs. Avoid crossover of digital and analog sig-
nals. 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 dedi-
cated to ground planes while signals are placed on the
solder side. Good decoupling is also important. All ana-
log supplies should be decoupled with 10μF tantalum
capacitors in parallel with 0.1μF capacitors to GND. To
achieve the best from these decoupling components, they
must be placed as close as possible to the device.
EVALUATING THE AD7450A/AD7440 PERFORMANCE
The evaluation board package includes a fully assembled
and tested evaluation board, documentation and software
for controlling the board from a PC via the Evaluation
Board Controller. The Evaluation Board Controller can
be used in conjunction with the AD7450A/40 Evaluation
board as well as many other Analog Devices evaluation
boards ending with the CB designator, to demonstrate/
evaluate the ac and dc performance of the AD7450A/40.
The software allows the user to perform ac (fast Fourier
Transform) and dc (Histogram of codes) tests on the
AD7450A/40. See the evaluation board technical note for
more information.
