Texas Instruments

Published : 06 May 13

Description

A new linear IC now provides the ultimate in highly stable voltage references. Now a new monolithic IC the LM199 out-performs zeners and can provide a 6.9 V reference with a temperature drift of less than 1 ppm/C° and excellent long term stability. This new IC uses a unique subsurface zener to achieve low noise and a highly stable breakdown. Included is an on-chip temperature stabilizer that ho
