DESCRIPTION
VRE107 Series Precision Voltage References provide
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 impovement
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 ac-
curacy, warm-up drift, line regulation, and long-term
stability, making the VRE107 series the most accurate
and stable 5 V references available.
VRE107 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 14-pin hermetic ceramic packages for
maximum long-term stablity. “M” versions are screened
for high reliability and quality.
Superior stability, accuracy, and quality make these
references ideal for precision applications such as A/D
and D/A converters, high accuracy test and measure-
ment instrumentation, and tranducer excitation.
