DESCRIPTION
VRE117 Series Precision Voltage References provide ultrastable +3.000V (VRE117), -3.000V (VRE118) and ±3.000V (VRE119) outputs with ±0.200 mV initial accuracy and temperature coefficient 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 developed by Thaler Corporation. Significant improvements have been made in other performance parameters as well, including initial accuracy, warm-up drift, line regulation, and long-term stability, making the VRE117 series the most accurate and stable 3.0V reference available.
