LM329 www.ti.com SNVS748F – MAY 2000 – REVISED APRIL 2013 LM329 Precision Reference Check for Samples: LM329 FEATURES 1 •2 0.6 mA to 15 mA Operating Current • 0.8Ω Dynamic Impedance at Any Current • Available With Temperature Coefficient of 0.01%/°C • 7μV Wideband Noise • 5% Initial Tolerance • 0.002% Long Term Stability • Low Cost • Subsurface Zener DESCRIPTION The LM329 is a precision multi-current temperaturecompensated 6.9V zener reference with dynamic impedance a factor of 10 to 100 less than discrete diodes. Constructed in a single silicon chip, the LM329 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 LM329 is available with a temperature coefficients of 0.01%/°C.
