10-Bit, 40MHz, Current/Voltage-Output DACs
ture stability, wide-band tuning, and past phase-contin-
uos frequency switching, the user may approach a
direct digital synthesis (DDS) AWG (Figure 8b). This
DDS loop supports standard waveforms that are repeti-
tive, such as sine, square, TTL, and triangular wave-
forms. DDS allows for precise control of the
data-stream input to the DAC. Data for one complete
output waveform cycle is sequentially stored in a RAM.
As the RAM addresses are changing, the DAC con-
verts the incoming data bits into a corresponding volt-
age waveform. The resulting output signal frequency is
proportional to the frequency rate at which the RAM
addresses are changed.

Grounding and power-supply decoupling strongly influ-
ence the MAX5181/MAX5184’s performance. Unwanted
digital crosstalk may couple through the input, refer-
ence, power-supply, and ground connections, which
may affect dynamic specifications like SNR or SFDR. In
addition, electromagnetic interference (EMI) can either
couple into or be generated by the MAX5181/
MAX5184. Therefore, grounding and power-supply
decoupling guidelines for high-speed, high-frequency
applications should be closely followed.
First, a multilayer PC board with separate ground and
power-supply planes is recommended. High-speed
signals should be run on controlled impedance lines
