DESCRIPTION
The REF02 is a precision 5V voltage reference. The drift is
laser trimmed to 10ppm/
°
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. The REF02
operates from a single supply with an input range of 8V to 40V
with a very low current drain of 1mA, and excellent temperature
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. Available package options are DIP-8 and SO-8. The
REF02 is an ideal choice for portable instrumentation,
temperature transducers, Analog-to-Digital (A/D) and Digital-
to-Analog (D/A) converters, and digital voltmeters.
