VRE117, VRE119

Precision Voltage Reference

FEATURES

DESCRIPTION

VRE117/119 Series Precision Voltage References pro-

vide ultrastable +3 V (VRE117), and ±3 V (VRE119)

output with ±300 µV initial accuracy and temperature

coefﬁcient as low as 0.73 ppm/°C over the full military

temperature range. This improvement in accuracy is

made possible by a unique, proprietary multipoint laser

compensation technique. Signiﬁcant improvements

have been made in other performance parameters as

well, including initial accuracy, warm-up drift, line regu-

lation, and long-term stability, making the VRE117/119

series the most accurate and stable 3 V reference

available.

♦ Very High Accuracy: ±3 V Output, ±300 µV

♦ Extremely Low Drift: 0.73 ppm/°C (-55°C to

+125°C)

♦ Low Warm-up Drift: 1 ppm Typical

♦ Excellent Stability: 6 ppm/1000 Hrs. Typical

♦ Excellent Line Regulation: 3 ppm/V Typical

♦ Hermetic 14-pin Ceramic DIP

♦ Military Processing Option

APPLICATIONS

♦ Precision A/D and D/A Converters

♦ Transducer Excitation

VRE117/119 devices are available in two operat-

ing 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.

♦ Accurate Comparator Threshold Reference

♦ High Resolution Servo Systems

♦ Digital Voltmeters

♦ High Precision Test and Measurement Instru-

ments

Superior stability, accuracy, and quality make these

references ideal for precision applications such as A/D

and D/A converters, high-accuracy test and measure-

ment instrumentation, and transducer excitation.
