PRELIMINARY TECHNICAL DATA
ADT7316/7317/7318
TERMINOLOGY
RELATIVE ACCURACY
Relative accuracy or integral nonlinearity (INL) is a mea-
sure of the maximum deviation, in LSBs, from a straight
line passing through the endpoints of the DAC transfer
function. Typical INL versus Code plots can be seen in
TPCs 1, 2, and 3.
DIFFERENTIAL NONLINEARITY
Differential Nonlinearity (DNL) is the difference be-
tween 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 and Temperature Sensor ADC is guaranteed
monotonic by design. Typical DAC DNL versus Code
plots can be seen in TPCs 4, 5, and 6.
OFFSET ERROR
This is a measure of the offset error of the DAC and the
output amplifier. (See Figures 5 and 6.) It can be negative
or positive. It is expressed in mV.
OFFSET ERROR MATCH
This is the difference in Offset Error between any two
channels.
GAIN ERROR
This is 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.
GAIN ERROR MATCH
This is the difference in Gain Error between any two
channels.
OFFSET ERROR DRIFT
This is a measure of the change in offset error with
changes in temperature. It is expressed in (ppm of full-
scale range)/
°
C.
GAIN ERROR DRIFT
This is a measure of the change in gain error with
changes in temperature. It 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 V
OUT
to a change in V
DD
for full-scale output of
the DAC. It is measured in dBs. V
REF
is held at 2 V and
V
DD
is varied ±10%.
DC CROSSTALK
This is the dc change in the output level of one DAC in
response to a change in the output of another DAC. It is
measured with a full-scale output change on one DAC
while monitoring another DAC. It is expressed in μV.
REFERENCE FEEDTHROUGH
This is the ratio of the amplitude of the signal at the
DAC output to the reference input when the DAC output
is not being updated (i.e.,
in dBs.
is high). It is expressed
CHANNEL-TO-CHANNEL ISOLATION
This is the ratio of the amplitude of the signal at the out-
put of one DAC to a sine wave on the reference input of
another DAC. It is measured in dBs.
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 register 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 transi-
tion (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 a DAC from the digital input
pins of the device but is measured when the DAC is not
being written to the. It is specified in nV secs and is mea-
sured with a full-scale change on the digital input pins,
i.e., from all 0s to all 1s or vice versa.
DIGITAL CROSSTALK
This is 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. It is measured in stand-alone mode and is
expressed in nV secs.
ANALOG CROSSTALK
This is the glitch impulse transferred to the output of one
DAC due to a change in the output of another 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
high. Then pulse
the output of the DAC whose digital code was not
changed. The area of the glitch is expressed in nV secs.
low and monitor
DAC-TO-DAC CROSSTALK
This is the glitch impulse transferred to the output of one
DAC due to a digital code change and subsequent out-
put change of another 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) with
low and monitoring the output of
another DAC. The energy of the glitch is expressed in nV
secs.
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 band-
width is the frequency at which the output amplitude falls
to 3 dB below the input.
