DESCRIPTION
VRE204 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 successive-approximation type Analog-to-Digital
Converters (ADCs). Specify an ADC with exceptional
temperature drift, which can only be as good as the
external reference used. The VRE204 combined with
the right ADC will provide the lowest drift data conver-
sion obtainable.
The VRE204 series is available in the military operat-
ing temperature range -55°C to +125°C, and two per-
formance grades. All devices are packaged in 20-ter-
minal LCC ceramic packages for maximum long-term
stability. These “M” versions are screened for high reli-
ability and quality.
Superior stability, accuracy, and quality make the
VRE204 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 VRE204.
