DESCRIPTION
VRE104 Series Precision Voltage References provide
ultrastable +4.5 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-ap-
proximation 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 refer-
ence used. The VRE104 combined with an ADC will
provide the lowest drift data conversion obtainable.
VRE104 series devices are available in two operat-
ing 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. âMâ 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 4.5 V reference. High-accuracy test and
measurement instrumentation, and transducer exci-
tation are some other applications which can benefit
from the high accuracy of the VRE104.
