  • Trimmed to High Accuracy: 0.05% Max
  • Industrial Temperature Range SO Package
  • Operates in Series or Shunt Mode
  • Pin Compatible with AD586, AD587
  • Output Sinks and Sources in Series Mode
  • Very Low Noise < 1ppm P-P (0.1Hz to 10Hz)
  • 100% Noise Tested
  • > 100dB Ripple Rejection

The LT1236 is a precision reference that combines ultralow drift and noise with excellent long-term stability and high output accuracy. The reference output will both source and sink up to 10mA and is almost totally immune to input voltage variations. Two voltages are available: 5V and 10V. The 10V version can be used as a shunt regulator (two-terminal zener) with the same precision characteristics as the three-terminal connection. Special care has been taken to minimize thermal regulation effects and temperature induced hysteresis.

The LT1236 combines both superior accuracy and temperature coefficient specifications with out the use of high power, on-chipheaters. The LT1236 references are based on a buried zener diode structure which eliminates noise and stability problems with surface breakdown devices. Further, a subsurface zener exhibits better temperature drift and time stability than even the best band-gap references.
