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.
