VRE202C Datasheet

Precision Surface Mount Reference Supplies


The VRE202C 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, warm-up drift, line regulation, and longterm stability, making the VRE202C the most accurate and stable 2.5 V surface mount references available. VRE202C Features • Very High Accuracy: +2.5 V Output, ±200 μV• Extremely Low Drift: 0.6 ppm/°C (25°C to +85°C)• Low Warm-up Drift: 1 ppm Typical• Excellent Stability: 6 ppm/1000 Hrs.
