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.
