DESCRIPTION

VRE210 Series Precision Voltage References provide

ultrastable +10 V outputs with ±0.5 mV initial accuracy

and temperature coefficient as low as 0.6 ppm/ºC 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 long term stability, making

the VRE210 series the most accurate and stable 10 V

surface mount references available.

VRE210 devices are available in two operating tem-

perature ranges, -25ºC to +85ºC and -55ºC to +125ºC,

and two electrical 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.
