AD5405
These DACs should have ample supply bypassing of 10 μF in
parallel with 0.1 μF on the supply located as close to the pack-
age as possible, ideally right up against the device. The 0.1 μF
capacitor should have low effective series resistance (ESR)
and effective series inductance (ESI), like the common ceramic
types that provide a low impedance path to ground at high
frequencies, to handle transient currents due to internal logic
switching. Low ESR 1 μF to 10 μF tantalum or electrolytic
capacitors should also be applied at the supplies to minimize
transient disturbance and filter out low frequency ripple.

Fast switching signals such as clocks should be shielded with
digital ground to avoid radiating noise to other parts of the
board, and 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 not always possible with a
double-sided board. In this technique, the component side of
the board is dedicated to the ground plane while signal traces
are placed on the soldered side.
It is good practice to employ 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 V
REF
and R
FB
should also be
matched to minimize gain error. To maximize high frequency
performance, the I-to-V amplifier should be located as close to
the device as possible.
EVALUATION BOARD FOR THE DACS
The evaluation board consists of a DAC and a current-to-
voltage amplifier, the AD8065. Included on the evaluation
board is a 10 V reference, the ADR01. An external reference
may also be applied via an SMB input.
The evaluation kit consists of a CD-ROM with self-installing
PC software to control the DAC. The software simply allows the
user to write a code to the device.
POWER SUPPLIES FOR
THE EVALUATION BOARD
The board requires ±12 V and 5 V supplies. The 12 V V
DD
and
V
SS
are used to power the output amplifier, while the 5 V is used
to power the DAC (V
DD1
) and transceivers (V
CC
).
Both supplies are decoupled to their respective ground plane
with 10
μ
F tantalum and 0.1
μ
F ceramic capacitors.
