Total Harmonic Distortion
Total harmonic distortion (THD) is the ratio of the RMS
sum of the first five harmonics of the input signal to the
fundamental itself. This is expressed as:
where V1 is the fundamental amplitude and V2 through
V5 are the 2nd- through 5th-order harmonics.
Spurious-Free Dynamic Range
Spurious-free dynamic range (SFDR) is the ratio of the
RMS amplitude of the fundamental (maximum signal
component) to the RMS value of the next-largest fre-
quency component.
Supplies, Layout, Grounding, and
Bypassing
Use printed circuit (PC) boards with separate analog
and digital ground planes. Do not use wire-wrap
boards. Connect the two ground planes together at the
MAX1067/MAX1068 AGND terminal. Isolate the digital
supply from the analog with a low-value resistor (10
)
or ferrite bead when the analog and digital supplies
come from the same source (Figure 25).
Constraints on sequencing the power supplies and
inputs are as follows:
Apply AGND before DGND.
Apply AIN_ and REF after AVDD and AGND are
present.
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 PC board
ground trace impedance of only 0.05
creates an error
voltage of about 250V and a 1 LSB error with a +4.096V
full-scale system.
The board layout should ensure that digital and analog
signal lines are kept separate. Do not run analog and dig-
ital lines (especially the SCLK and DOUT) parallel to one
another. If one must cross another, do so at right angles.
The ADC’s 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 0.1F capacitor in parallel with a 1F to 10F
low-ESR capacitor. Keep capacitor leads short for best
supply-noise rejection.
