The REF02 is a precision 5V voltage reference. The
drift is laser trimmed to 8.5ppm/°C max over the
extended industrial and military temperature range.
The REF02 provides a stable 5V output that can be
externally adjusted over a
±6%
range with minimal
effect on temperature stability. REF02 operates from a
single supply with an input range of 8V to 40V with a
very low current drain of 1mA, and excellent tempera-
ture stability due to an improved design. Excellent line
and load regulation, low noise, low power, and low
cost make the REF02 the best choice whenever a 5V
voltage reference is required. All popular package
options are available: plastic DIP, and SOIC. The
REF02 is an ideal choice for portable instrumentation,
temperature transducers, A/D and D/A converters, and
digital voltmeter.

ELECTROSTATIC
DISCHARGE SENSITIVITY
This integrated circuit can be damaged by ESD. Burr-Brown
recommends that all integrated circuits be handled with
appropriate precautions. Failure to observe proper handling
and installation procedures can cause damage.
ESD damage can range from subtle performance degradation
to complete device failure. Precision integrated circuits may
be more susceptible to damage because very small parametric
changes could cause the device not to meet its published
specifications.
