PCB LAYOUT AND POWER SUPPLY DECOUPLING
In any circuit where accuracy is important, careful considera-
tion of the power supply and ground return layout helps to
ensure the rated performance. The printed circuit board on
which the AD5415 is mounted should be designed so that the
analog and digital sections are separated and confined to
certain areas of the board. If the DAC is in a system where
multiple devices require an AGND-to-DGND connection, the
connection should be made at one point only. The star ground
point should be established as close as possible to the device.
The DAC should have ample supply bypassing of 10 F in
parallel with 0.1 F on the supply located as close as possible to
the package, ideally right up against the device. The 0.1 F
capacitor should have low effective series resistance (ESR) and
low effective series inductance (ESI), like the common ceramic
types of capacitors that provide a low impedance path to ground
at high frequencies, to handle transient currents due to internal
logic switching. Low ESR 1 F to 10 F tantalum or electrolytic
capacitors should also be applied at the supplies to minimize
transient disturbance and filter out low frequency ripple.
Components, such as clocks, that produce fast-switching signals
should be shielded with digital ground to avoid radiating noise
to other parts of the board, and they should never be run near
the reference inputs.
Avoid crossover of digital and analog signals. Traces on
opposite sides of the board should run at right angles to each
other. This reduces the effects of feedthrough on the board. A
microstrip technique is by far the best, but its use is not always
possible with a double-sided board. In this technique, the
component side of the board is dedicated to the ground plane,
and signal traces are placed on the soldered side.
It is good practice to use compact, minimum lead length PCB
layout design. Leads to the input should be as short as possible
to minimize IR drops and stray inductance.
The PCB metal traces between VREF and RFB should also be
matched to minimize gain error. To maximize high frequency
performance, the I-to-V amplifier should be located as close as
possible to the device.
