FIGURE 10. Bipolar Operation with the DAC8531.
The power applied to VDD should be well regulated and low
noise. Switching power supplies and DC/DC converters will
often have high-frequency glitches or spikes riding on the
output voltage. In addition, digital components can create
similar high-frequency spikes as their internal logic switches
states. This noise can easily couple into the DAC output
voltage through various paths between the power connec-
tions and analog output.
As with the GND connection, VDD should be connected to a
+5V power-supply plane or trace that is separate from the
connection for digital logic until they are connected at the
power-entry point. In addition, the 1
F to 10F and 0.1F
bypass capacitors are strongly recommended. In some situ-
ations, additional bypassing may be required, such as a
100
F electrolytic capacitor or even a “Pi” filter made up of
inductors and capacitors—all designed to essentially low-
pass filter the +5V supply, removing the high-frequency
noise.
