VRE104

DESCRIPTION

VRE104 Series Precision Voltage References pro-

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

initial accuracy and temperature coefficient as low as

0.74ppm/°C over the full military temperature range.

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.

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.
