DESCRIPTION

VRE114 Series Precision Voltage References

provide ultrastable +1.500V (VRE114), -1.500V

(VRE115) and ±1.500V (VRE116) outputs with

±150

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 VRE114 series the

most

available.

VRE114/115/116 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.

• VERY HIGH ACCURACY: 1.500 V OUTPUT ±150 µV
