DESCRIPTION
VRE117 Series Precision Voltage References
provide ultrastable +3.000V (VRE117), -3.000V
SELECTION GUIDE
(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
VRE118C -3.0V -25°C to +85°C 200 µV
other performance parameters as well, including
VRE118CA -3.0V -25°C to +85°C 100 µV
initial accuracy, warm-up drift, line regulation, and
VRE118M -3.0V -55°C to +125°C 400 µV
long-term stability, making the VRE117 series the
VRE118MA -3.0V -55°C to +125°C 200 µV
most accurate and stable 3.0V reference
available.

VRE117/118/119 devices are available in two
VRE119M ±3.0V -55°C to +125°C 400 µV
operating temperature ranges, -25°C to +85°C
VRE119MA ±3.0V -55°C to +125°C 200 µV
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.
