DESCRIPTION

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.
