TERMINOLOGY
Relative Accuracy or Integral Nonlinearity (INL)
For the DAC, it is a measure, in LSB, of the maximum deviation
from a straight line passing through the endpoints of the DAC
transfer function. Typical INL vs. code plots are shown in
Differential Nonlinearity (DNL)
The difference between the measured change and the ideal 1 LSB
change between any two adjacent codes. A specified differential
nonlinearity of 1 LSB maximum ensures monotonicity. This DAC
is guaranteed monotonic by design. Typical DNL vs. code plots
Offset Error
A measure of the offset error of the DAC and the output ampli-
Offset error is expressed in mV.
Gain Error
A measure of the span error of the DAC. It is the deviation in
slope of the actual DAC transfer characteristic from the ideal
expressed as a percentage of the full-scale range.
Offset Error Drift
A measure of the change in offset error with changes in
temperature. Offset error drift is expressed in (ppm of full-scale
range)/°C.
Gain Error Drift
A measure of the change in gain error with changes in
temperature. Gain error drift is expressed in (ppm of full-scale
range)/°C.
DC Power Supply Rejection Ratio (PSRR)
This indicates how the output of the DAC is affected by changes
in the supply voltage. PSRR is the ratio of the change in VOUT to
a change in VDD for full-scale output of the DAC. PSRR is
measured in dB. VREF is held at 2 V and VDD is varied 10%.
DC Crosstalk
The dc change in the output level of one DAC at midscale in
response to a full-scale code change (all 0s to all 1s, and vice
versa) and output change of another DAC. DC crosstalk is
expressed in μV.
Reference Feedthrough
The ratio of the amplitude of the signal at the DAC output to
the reference input when the DAC output is not being updated,
that is, when LDAC is high. Reference feedthrough is expressed
in dB.
Channel-to-Channel Isolation
The ratio of the amplitude of the signal at the output of one
DAC to a sine wave on the reference input of another DAC.
Channel-to-channel isolation is measured in dB.
Major-Code Transition Glitch Energy
The energy of the impulse injected into the analog output when
the code in the DAC register changes state. This energy is
normally specified as the area of the glitch in nV-s and is
measured when the digital code is changed by 1 LSB at the
major carry transition (011...11 to 100...00 or 100...00 to
011...11).
Digital Feedthrough
A measure of the impulse injected into the analog output of a
DAC from the digital input pins of the device when the DAC
output is not being updated. Digital feedthrough is specified in
nV-s and is measured with a worst-case change on the digital
input pins (that is, from all 0s to all 1s, and vice versa).
Digital Crosstalk
The glitch impulse transferred to the output of one DAC at
midscale in response to a full-scale code change (all 0s to all 1s,
and vice versa) in the input register of another DAC. The
energy of the glitch is expressed in nV-s.
Analog Crosstalk
The glitch impulse transferred to the output of one DAC due to
a change in the output of another DAC. Analog crosstalk is
measured by loading one of the DACs with a full-scale code
change (all 0s to all 1s, and vice versa) while keeping LDAC
high and then pulsing LDAC low and monitoring the output of
the DAC whose digital code has not changed. The energy of the
glitch is expressed in nV-s.
DAC-to-DAC Crosstalk
The glitch impulse transferred to the output of one DAC due to
a digital code change and subsequent output change of another
DAC. This includes both digital and analog crosstalk. Crosstalk
is measured by loading one of the DACs with a full-scale code
change (all 0s to all 1s, and vice versa) with LDAC low and then
monitoring the output of another DAC. The energy of the glitch
is expressed in nV-s.
Multiplying Bandwidth
The amplifiers within the DAC have a finite bandwidth. The
multiplying bandwidth is a measure of this. A sine wave on the
reference (with full-scale code loaded to the DAC) appears on
the output. The multiplying bandwidth is the frequency at
which the output amplitude falls to 3 dB below the input.
Total Harmonic Distortion (THD)
The difference between an ideal sine wave and its attenuated
version using the DAC. The sine wave is used as the reference
for the DAC, and the THD is a measure of the harmonics
present on the DAC output. THD is measured in dB.
