VRE202C Datasheet PDF - Cirrus Logic

DESCRIPTION
VRE202 Series Precision Voltage References provide ultrastable +2.5 V outputs with ±200 μV 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. 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.
