DESCRIPTION
Precision Voltage Reference
FEATURES
♦ Very High Accuracy:
±
10 V Output, ±1.0 mV
♦ Extremely Low Drift: 1.0 ppm/ºC (-55ºC to
+125ºC)
♦ Low Warm-up Drift: 1.0 ppm Typical
♦ Excellent Stability: 6 ppm/1000 Hrs. Typical
♦ Excellent Line Regulation: 3 ppm/V Typical
♦ Hermetic 14-pin Ceramic DIP
♦ Military Processing Option
VRE100 Series Precision Voltage References provide
ultrastable +10 V (VRE100), -10 V (VRE101) and ±10
V (VRE102) outputs with ±1.0 mV initial accuracy and
temperature coefficient as low as 1.0 ppm/°C over the
full military temperature range. This improvement in
accuracy is made possible by a unique, proprietary
multipoint laser compensation technique.
Significant improvements have been made in other
performance parameters as well, including initial ac-
curacy, warm-up drift, line regulation, and long-term
stability, making the VRE100 series the most accurate
and stable 10 V reference available.
VRE100/101/102 devices are available in two oper-
ating 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 these
references ideal for precision applications such as A/D
and D/A converters, high-accuracy test and measure-
ment instrumentation, and transducer excitation.
