HIGH PRECISION TEST and
MEASUREMENT INSTRUMENTS
DESCRIPTION
VRE202 Series Precision Voltage References
provide ultrastable +2.5000V outputs with 鹵200
碌V initial accuracy and temperature coefficient as
low as 0.6 ppm/擄C over the full military
temperature range. This improvement in accuracy
is made possible by a unique, proprietary
multipoint
laser
compensation
technique
developed by Thaler Corporation. 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 VRE202 series the most
accurate and stable 2.5V surface mount
references available.
VRE202 devices are available in two operating
temperature ranges, -25擄C to +85擄C and -55擄C to
+125擄C, 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.
