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
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.
