DESCRIPTION
VRE205 Series Precision Voltage References provides ultrastable ±5 V outputs with ±0.4 mV initial accuracy and temperature coeffcient as low as 0.6 ppm/°C over the full military temperature range. This improvement in accuracy is made possible by a unique, proprietary multipoint laser compensation technique. Signifcant improvements have been made in other performance parameters as well, including initial accuracy, warm-up drift, line regulation, and longterm stability, making the VRE205 series the most accurate and stable 5 V references available.
