1 / 8 page LM199/LM399 LM199A/LM399A 1 LM199399fb Precision Reference The LM199/LM399 precision shunt reference features excellent temperature stability over a wide range of volt- age, temperature and operating current conditions. A stabilizing heater is incorporated with the active Zener on a monolithic substrate which nearly eliminates changes in voltage with temperature. The subsurface Zener operates over a current range of 0.5mA to 10mA, and offers minimal noise and excellent long-term stability. Ideal applications for the LM199/LM399 include digital volt- meters, precision calibration equipment, current sources and a variety of other precision low cost references. A 10V buffered reference application is shown below. ■ Precision Voltage Reference for Multimeters ■ Calibration Equipment Voltage Standards ■ Laboratory Measurement Equipment ■ Industrial Monitor/Control Instruments ■ High Accuracy Data Converters ■ 6.95V Shunt Reference ■ Guaranteed 0.5ppm/°C Temperature Coefficient ■ Guaranteed 1 Ω Maximum Dynamic Impedance ■ Guaranteed 20µVRMS Maximum Noise ■ Guaranteed Initial Tolerance of 2% ■ Wide Operating Current Range ■ Available in 4-Lead TO-46 Metal Can 10V Buffered Reference APPLICATIO S FEATURES DESCRIPTIO TYPICAL APPLICATIO , LTC and LT are registered trademarks of Linear Technology Corporation.
