FEATURES

SELECTION GUIDE

VRE202 Series Precision Voltage References

provide ultrastable +2.5000V outputs with ±200

µV 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

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°C to +85°C and -55°C to

+125°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.
