FEATURES
SELECTION GUIDE
VRE104 Series Precision Voltage References
provide ultrastable +4.500 V outputs with up to
±0.4
mV
initial
accuracy
and
temperature
coefficient as low as 0.6 ppm/°C over the full
military temperature range.
These references are specifically designed to be
used with the Crystal Semiconductor line of
successive-approximation type Analog to Digital
Converters (ADCs). This line of ADCs sets new
standards for temperature drift, which can only be
as good as the external reference used. The
Thaler VRE104 combined with a Crystal ADC will
provide
the
lowest
drift
data
conversion
obtainable.

VRE104 series devices are available in two operating temperature ranges, -25°C to +85°C and -55°C to
+125°C, and two performance grades. All devices are packaged in 14-pin hermetic ceramic packages for
maximum long-term stability. "M" versions are screened for high reliability and quality.
Superior stability, accuracy, and quality make the VRE104 ideal for all precision applications which may
require a 4.5V reference. High-accuracy test and measurement instrumentation, and transducer excitation are
some other applications which can benefit from the high accuracy of the VRE104.
