VRE205MA

VRE205MA Datasheet


VRE205 Series Precision Voltage References provides ultrastable +5 V outputs with mV initial accuracy and temperature coefficient as low as 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 accuracy, warm-up drift, line regulation, and longterm stability, making the VRE205 series the most accurate and stable 5 V references available.
