Description

VRE117 Series Precision Voltage References SELECTION GUIDE 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/ 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 to +85 and -55 to +125, 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 VRE117 ideal for precision applications such as A/D and D/A converters, high-accuracy test and measurement instrumentation, and transducer excitation.
