VRE100, VRE101, VRE102
DESCRIPTION
VRE100 Series Precision Voltage References provide
ultrastable +10 V (VRE100) and ±10 V (VRE102) out-
puts with ±1.0 mV initial accuracy and temperature co-
efcient as low as 1.09 ppm/°C over the full military
temperature range. This improvement in accuracy is
made possible by a unique, proprietary multipoint laser
compensation technique.
Signicant 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 VRE100 series the most accurate
and stable 10 V reference available.
VRE100/102 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 stability. “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 transducer excitation.
