The LM329AZ is a temperature-compensated 6.9V precision shunt voltage reference manufactured by Analog Devices Inc. It operates within an ambient temperature range of 0°C to 70°C and utilizes a buried zener design for low noise. Key electrical specifications include a reverse breakdown voltage of 6.7V to 7.2V, a maximum dynamic impedance of 1W, and wideband noise of 20mV RMS. The device supports an operating current range from 0.6mA to 15mA with a guaranteed temperature coefficient of 10ppm/°C.
Verify component authenticity and datasheet alignment before procurement. Confirm that the specific ordering suffix matches the required package style and temperature grade. Ensure supply chain sources are authorized distributors to guarantee part integrity and traceability.
Select this component when a stable 6.9V reference is required in through-hole TO-92 packages. Consider the 10ppm/°C temperature coefficient and 0.6mA to 15mA operating current range against application needs. Evaluate thermal management requirements based on the specified junction-to-ambient thermal resistance.
The LM329AZ belongs to the LM129/LM329 family of precision voltage references. This series offers multiple temperature coefficient grades and package options, including metal cans and plastic TO-92 styles. The LM329 variant specifically targets commercial temperature ranges, distinguishing it from the extended range LM129.
Consult Linear Technology marketing for availability of alternate source parts if the LM329AZ is discontinued. The datasheet notes the Z package as an alternative source option for obsolete packages.
