VRE107 VRE107VRE107 Precision Voltage Reference FEATURES DESCRIPTION VRE107 Series Precision Voltage References provide Very High Accuracy: 5 V, 0.8 mV ultrastable 5 V outputs with 0.8 mV initial accuracy Extremely Low Drift: 1.33 ppm/C (-55C to and temperature coefficient as low as 1.33 ppm/C +125C) over the full military temperature range. This impove- Excellent Stability: 6 ppm/1000 Hrs. Typical ment in accuracy is made possible by a unique, propri- Excellent Line Regulation: 6 ppm/V Typical etary multipoint laser compensation technique. Wide Supply Range: 13.5 V to 22 V Significant improvements have been made in other Hermetic 14-pin Ceramic DIP performance parameters as well, including initial ac- Military Processing Option curacy, warm-up drift, line regulation, and long-term stability, making the VRE107 series the most accurate APPLICATIONS and stable 5 V references available. Precision A/D and D/A Converters Transducer Excitation VRE107 series devices are available in two perfor- Accurate Comparator Threshold Reference mance grades. All devices are packaged in 14-pin High Resolution Servo Systems hermetic ceramic packages for maximum long-term stablity. M versions are screened for high reliability Digital Voltmeters and quality. High Precision Test and Measurement Instru- ments Superior stability, accuracy, and quality make these references ideal for precision applications such as A/D and D/A converters, high accuracy test and measure- ment instrumentation, and tranducer excitation.
