DESCRIPTION
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.
