VRE202中文资料凌云逻辑数据手册PDF规格书

DESCRIPTION

VRE202 Series Precision Voltage References provide ultrastable +2.5 V outputs with ±300 μV initial accuracy and temperature coefficient as low as 0.73 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, warmup drift, line regulation, and longterm stability, making the VRE202 series the most accurate and stable 2.5 V surface mount references available.
