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.
A new subsurface breakdown zener used in the LM129 gives lower noise
and better long-term stability than conventional IC zeners. Further the
zener and temperature compensating transistor are made by a planar
process so they are immune to problems that plague ordinary zeners.
For example, there is virtually no voltage shift in zener voltage due to
temperature cycling and the device is insensitive to stress on the leads.
The LM129 can be used in place of conventional zeners with improved
performance. The low dynamic impedance simplifies biasing and the wide
operating current allows the replacement of many zener types.
