LM399H#PBF

LM399 is a precision shunt reference. It features excellent temperature stability over a wide range of voltage, 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 device include digital voltmeters, precision calibration equipment, current sources and a variety of other precision low cost references. It is used in application such as precision voltage reference for multimeters, calibration equipment voltage standards, laboratory measurement equipment, industrial monitor/control instruments, high accuracy data converters etc.
