VRE202 General Description

VRE202 Series Precision Voltage References provide ultrastable +2.5000V 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 developed by Thaler Corporation. Significant improvements have been made in other performance parameters as well, including initial accuracy, warm-up drift, line regulation, and longterm stability, making the VRE202 series the most accurate and stable 2.5V surface mount references available.

VRE202 devices are available in two operating temperature ranges, -25°C to +85°C and -55°C to +125°C, and two electrical performance grades. All devices are packaged in 20 terminal ceramic LCC packages for maximum long-term stability. "M" versions are screened for high reliability and quality.
