Precision Voltage Reference

FEATURES

DESCRIPTION

VRE104 Series Precision Voltage References provide

ultrastable +4.5 V outputs with up to ±0.8 mV initial

accuracy and temperature coefﬁcient as low as 1.48

ppm/°C over the full military temperature range.

♦ Very High Accuracy: +4.5 V Output, ±0.8 mV

♦ Extremely Low Drift: 1.48 ppm/°C (-55°C to

+125°C)

♦ Excellent Stability: 6 ppm/1000 Hrs. Typical

♦ Excellent Line Regulation: 6 ppm/V Typical

♦ Wide Supply Range: ±13.5 to ±22.0 V

♦ Hermetic 14-pin Ceramic DIP

These references are speciﬁcally designed to be used

with the Crystal Semiconductor line of successive-ap-

proximation type Analog to Digital Converters (ADCs).

This line of ADCs sets new standards for temperature

drift, which can only be as good as the external refer-

ence used. The VRE104 combined with an ADC will

provide the lowest drift data conversion obtainable.

♦ Military Processing Options

APPLICATIONS

♦ Precision A/D And D/A Converters

♦ Transducer Excitation

♦ Accurate Comparator Threshold Reference

♦ High Resolution Servo Systems

♦ Digital Voltmeters

♦ High Precision Test and Measurement Instru-

ments

VRE104 series 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.

Superior stability, accuracy, and quality make the

VRE104 ideal for all precision applications which may

require a 4.5 V reference. High-accuracy test and

measurement instrumentation, and transducer exci-

tation are some other applications which can beneﬁt

from the high accuracy of the VRE104.
