MAJOR-CODE TRANSITION GLITCH ENERGY
Major-code transition glitch energy is the energy of the impulse
injected into the analog output when the code in the DAC regis-
ter changes state. It is normally specified as the area of the glitch
in nV-secs 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
Digital feedthrough is a measure of the impulse injected into the
analog output of the DAC from the digital input pins of the
device, but is measured when the DAC is not being written to
(SYNC held high). It is specified in nV secs and is measured
with a full-scale change on the digital input pins, i.e., from all 0s
to all 1s and vice versa.
ANALOG CROSSTALK
This is the glitch impulse transferred to the output of one DAC
due to a change in the output of the other DAC. It is measured
by loading one of the input registers with a full-scale code
change (all 0s to all 1s and vice versa) while keeping LDAC
high. Then pulse LDAC low and monitor the output of the
DAC whose digital code was not changed. The area of the glitch
is expressed in nV-secs.
DAC-TO-DAC CROSSTALK
This is the glitch impulse transferred to the output of one DAC
due to a digital code change and subsequent output change of
the other DAC. This includes both digital and analog crosstalk.
It 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 low
and monitoring the output of the other DAC. The area of the
glitch is expressed in nV-secs.
DC CROSSTALK
This is the dc change in the output level of one DAC in re-
sponse to a change in the output of the other DAC. It is mea-
sured with a full-scale output change on one DAC while
monitoring the other DAC. It is expressed in
µV.
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. It is
measured in dBs. VREF is held at +2 V and VDD is varied
±10%.
REFERENCE FEEDTHROUGH
This is the ratio of the amplitude of the signal at the DAC out-
put to the reference input when the DAC output is not being
updated (i.e., LDAC is high). It is expressed in dBs.
TOTAL HARMONIC DISTORTION
This is the difference between an ideal sine wave and its attenu-
ated version using the DAC. The sine wave is used as the refer-
ence for the DAC and the THD is a measure of the harmonics
present on the DAC output. It is measured in dBs.
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.
CHANNEL-TO-CHANNEL ISOLATION
This is a ratio of the amplitude of the signal at the output of one
DAC to a sine wave on the reference input of the other DAC. It
is measured in dBs.
