LM129/LM329 Precision Reference March 2000 LM129/LM329 Precision Reference General Description The LM129 and LM329 family are precision multi-current temperature-compensated 6.
9V zener references with dynamic impedances a factor of 10 to 100 less than discrete diodes.
Constructed in a single silicon chip, the LM129 uses active circuitry to buffer the internal zener allowing the device to operate over a 0.
5 mA to 15 mA range with virtually no change in performance.
The LM129 and LM329 are available with selected temperature coefficients of 0.
001, 0.
002, 0.
005 and 0.
01%/˚C.
These references also have excellent long term stability and low noise.
