DESCRIPTION

VRE210 Series Precision Voltage References
provide ultrastable +10.000V outputs with ±0.3
mV initial accuracy and temperature coefficient
as low as 0.5 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 VRE210 series the
most accurate and stable 10V surface mount
references available.

APPLICATIONS

• PRECISION A/D and D/A CONVERTERS

• TRANSDUCER EXCITATION

• ACCURATE COMPARATOR THRESHOLD
REFERENCE

• HIGH RESOLUTION SERVO SYSTEMS

• DIGITAL VOLTMETERS

• HIGH PRECISION TEST and
MEASUREMENT INSTRUMENTS

VRE210 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.
