DESCRIPTION

VRE205 Series Precision Voltage References provides

ultrastable ±5 V outputs with ±0.4 mV initial accuracy

and temperature coefficient as low as 0.6 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 regulation, and longterm stability, making the

VRE205 series the most accurate and stable 5 V refer-

ences available.

VRE205 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 20-terminal ceramic LCC packages

for maximum long-term stability. “M” versions are

screened for high reliability and quality.
