APPLICATION INFORMATION
power-supply bypassing and ground management
Printed-circuit boards that use separate analog and digital ground planes offer the best system performance.
Wire-wrap boards do not perform well and should not be used. The two ground planes should be connected
together at the low-impedance power-supply source. The best ground connection may be achieved by
connecting the DAC AGND terminal to the system analog ground plane, making sure that analog ground
currents are well managed and there are negligible voltage drops across the ground plane.
A 0.1-
μ
F ceramic-capacitor bypass should be connected between V
DD
and AGND and mounted with short leads
as close as possible to the device. Use of ferrite beads may further isolate the system analog supply from the
digital power supply.
Figure 16 shows the ground plane layout and bypassing technique.

definitions of specifications and terminology
integral nonlinearity (INL)
The relative accuracy or integral nonlinearity (INL), sometimes referred to as linearity error, is the maximum
deviation of the output from the line between zero and full scale excluding the effects of zero code and full-scale
errors.
differential nonlinearity (DNL)
The differential nonlinearity (DNL), sometimes referred to as differential error, is the difference between the
measured and ideal 1 LSB amplitude change of any two adjacent codes. Monotonic means the output voltage
changes in the same direction (or remains constant) as a change in the digital input code.
zero-scale error (E
ZS
)
Zero-scale error is defined as the deviation of the output from 0 V at a digital input value of 0.
gain error (E
G
)
Gain error is the error in slope of the DAC transfer function.
total harmonic distortion (THD)
THD is the ratio of the rms value of the first six harmonic components to the value of the fundamental signal.
The value for THD is expressed in decibels.
signal-to-noise ratio + distortion (S/N+D)
S/N+D is the ratio of the rms value of the output signal to the rms sum of all other spectral components below
the Nyquist frequency, including harmonics but excluding dc. The value for S/N+D is expressed in decibels.
