Product Summary
The LM129AH is a precision multi-current temperature-compensated 6.9V zener reference with dynamic impedances a factor of 10 to 100 less than discrete diodes. Constructed in a single silicon chip, the LM129AH 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 device is available with selected temperature coefficients of 0.001, 0.002, 0.005 and 0.01%/℃. The reference LM129AH also has excellent long term stability and low noise. A new subsurface breakdown zener used in the LM129AH gives lower noise and better long-term stability than conventional IC zeners. The device 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.
