DESCRIPTION
VRE110 Series Precision Voltage References
provide ultrastable +2.500V (VRE110), -2.500V
(VRE101) and ±2.500V (VRE102) outputs with
±200
coefficient as low as 0.8 ppm/°C over the full
military temperature range. This improvement in
accuracy
proprietary
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 VRE110 series the
most
available.
VRE110/111/112 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.

... To remove this residual error, Thaler Corporation has developed a nonlinear compensation network of thermistors and resistors that is used in the VRE110 series references. This eliminates most of the nonlinearity in the voltage vs. temperature function. By then adjusting the slope, Thaler Corporation produces a very stable voltage over wide temperature ranges ...
