FEATURES
SELECTION GUIDE
VRE117 Series Precision Voltage References
provide ultrastable +3.000V (VRE117), -3.000V
(VRE118) and ±3.000V (VRE119) outputs with
±0.200 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
developed
by
Thaler
Corporation.
Significant improvements have been made in
other performance parameters as well, including
initial accuracy, warm-up drift, line regulation, and
long-term stability, making the VRE117 series the
most
accurate
and
stable
3.0V
reference
available.
VRE117/118/119 devices are available in two
operating 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 measurement instrumentation, and transducer excitation.
