DESCRIPTION
VRE204 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.
SELECTION GUIDE
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 VRE204 combined with a Crystal ADC will
provide the lowest drift data conversion
obtainable.

VRE204 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 20 terminal LCC ceramic packages
for maximum long-term stability. "M" versions are screened for high reliability and quality.
Superior stability, accuracy, and quality make the VRE204 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 VRE204.
