DESCRIPTION
VRE205 Series Precision Voltage References provides
ultrastable ±5 V outputs with ±0.4 mV initial accuracy
and temperature coefficient as low as 0.6 ppm/°C over
the full military temperature range. This improvement
in accuracy is made possible by a unique, proprietary
multipoint laser compensation technique. Significant
improvements have been made in other performance
parameters as well, including initial accuracy, warm-up
drift, line regulation, and longterm stability, making the
VRE205 series the most accurate and stable 5 V refer-
ences available.
VRE205 series devices are available in two operat-
ing temperature ranges, -25°C to +85°C and -55°C
to +125°C, and two performance grades. All devices
are packaged in 20-terminal ceramic LCC packages
for maximum long-term stability. “M” versions are
screened for high reliability and quality.
