ELECTROSTATIC
DISCHARGE SENSITIVITY
The DAC7541A is an ESD (electrostatic discharge) sensi-
tive device. The digital control inputs have a special FET
structure, which turns on when the input exceeds the supply
by 18V, to minimize ESD damage. However, permanent
damage may occur on unconnected devices subject to high
energy electrostatic fields. When not in use, devices must be
stored in conductive foam or shunts. The protective foam
should be discharged to the destination socket before
devices are removed.
BURN-IN SCREENING
Burn-in screening is an option available for the models in the
Ordering Information table. Burn-in duration is 160 hours at
the indicated temperature (or equivalent combination of time
and temperature).
All units are tested after burn-in to ensure that grade speci-
fications are met. To order burn-in, add “-BI” to the base
model number.

DISCUSSION
OF SPECIFICATIONS
RELATIVE ACCURACY
This term (also known as linearity) describes the transfer
function of analog output to digital input code. The linearity
error describes the deviation from a straight line between
zero and full scale.
DIFFERENTIAL NONLINEARITY
Differential nonlinearity is the deviation from an ideal 1LSB
change in the output, from one adjacent output state to the
next. A differential nonlinearity specification of
±1.0LSB
guarantees monotonicity.
GAIN ERROR
Gain error is the difference in measure of full-scale output
versus the ideal DAC output. The ideal output for the
DAC7541A is –(4095/4096)
X
(V
REF
). Gain error may be
adjusted to zero using external trims.
OUTPUT LEAKAGE CURRENT
The measure of current which appears at Out
1
with the DAC
loaded with all zeros, or at Out
2
with the DAC loaded with
all ones.
MULTIPLYING FEEDTHROUGH ERROR
This is the AC error output due to capacitive feedthrough
from V
REF
to Out
1
with the DAC loaded with all zeros. This
test is performed at 10kHz.
OUTPUT CURRENT SETTLING TIME
This is the time required for the output to settle to a tolerance
of
±0.5LSB
of final value from a change in code of all zeros
to all ones, or all ones to all zeros.
PROPAGATION DELAY
This is the measure of the delay of the internal circuitry and
is measured as the time from a digital code change to the
point at which the output reaches 90% of final value.
DIGITAL-TO-ANALOG GLITCH IMPULSE
This is the measure of the area of the glitch energy measured
in nV-seconds. Key contributions to glitch energy are digital
