LM129BH Description

Short technical summary and product information.

The LM129BH is a precision voltage reference IC from National Semiconductor, providing a stable 6.9V output. It features a guaranteed temperature coefficient of 10ppm/°C and a maximum dynamic impedance of 1Ω, ensuring excellent stability across varying conditions.

 

Designed with a "buried Zener" structure, the LM129BH minimizes surface noise, resulting in superior noise performance with a guaranteed wideband noise of 20μV. It operates within a wide current range of 0.6mA to 15mA, making it suitable for various applications.

 

Available in TO-46 metal can and TO-92 package styles, the LM129BH is designed for through-hole mounting. The LM329 series operates from 0°C to 70°C, while the LM129 series has a wider operating range of -55°C to 125°C.

 

This voltage reference is ideal for applications requiring high accuracy and stability, such as transducers, A/D and D/A converters, calibration standards, and general instrumentation.
