VRE102 RoHS Precision Voltage Reference COMPLIANT FEATURES Very High Accuracy: 10V Output, 1.0mV Extremely Low Drift: 1.09ppm/C (-55C to +125C) Low Warm-up Drift: 1.0ppm Typical Excellent Stability: 6ppm/1000 Hrs. Typical Excellent Line Regulation: 3ppm/V Typical Hermetic 14-pin Ceramic DIP Military Processing Option APPLICATIONS Precision A/D and D/A Converters Transducer Excitation Accurate Comparator Threshold Reference High Resolution Servo Systems Digital Voltmeters High Precision Test and Measurement Instruments DESCRIPTION VRE102 Precision Voltage Reference provides ultrastable 10V outputs with 1.0mV initial accuracy and temperature coefficient as low as 1.09ppm/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 long-term stability, making the VRE102 the most accurate and stable 10V reference available. VRE100/102 devices are available in two operating temperature ranges, -25C to +85C and -55C to +125C, and two performance grades. All devices are packaged in 14-pin hermetic ceramic packages for max- imum long-term stability. M versions are screened for high reliability and quality. Superior stability, accuracy, and quality make this reference ideal for precision applications such as A/D and D/A converters, high-accuracy test and measurement instrumentation, and transducer excitation.
