Figure 14. Powering AVDD and DVDD from a Single Supply
Supplies, Layout, Grounding, and Bypassing
Use PCBs with separate analog and digital ground
planes. Do not use wire-wrap boards. Connect the two
ground planes together at the MAX11100. Isolate the
digital supply from the analog with a low-value resistor
(10I) or ferrite bead when the analog and digital sup-
plies come from the same source (Figure 14).
Constraints on sequencing the power supplies and
inputs are as follows:
U
Apply AGND before DGND.
U
Apply AIN and REF after AVDD and AGND are present.
U
DVDD is independent of the supply sequencing.
Ensure that digital return currents do not pass through
the analog ground and that return-current paths are
low impedance. A 5mA current flowing through a PCB
ground trace impedance of only 0.05I creates an error
voltage of about 250FV, 4 LSB error with a +4V full-scale
system.
The board layout should ensure that digital and analog
signal lines are kept separate. Do not run analog and dig-
ital (especially the SCLK and DOUT) lines parallel to one
another. If one must cross another, do so at right angles.
The ADCs high-speed comparator is sensitive to high-
frequency noise on the AVDD power supply. Bypass an
excessively noisy supply to the analog ground plane with
a 0.1FF capacitor in parallel with a 1FF to 10FF low-ESR
capacitor. Keep capacitor leads short for best supply-
noise rejection.
