VRE202CA Datasheet
VRE202 Series Precision Voltage References provide ultrastable V outputs with ±200 uV initial accuracy and temperature coefficient as low as 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 V surface mount references available.

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 V 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.
