... Certified Long Term Drift The National Semiconductor LM199AH-20, LM299AH-20, and LM399AH-50 are ultra-stable Zener references specially selected from the production runs of LM199AH, LM299AH, LM399AH and tested to confirm a long-term stability of 20, 20 ppm per 1000 hours, respectively. The devices are measured every 168 hours and the voltage of each device is logged and compared in such a way as to show the deviation from its initial value ...
