Description

Most H (Metal Can), J (Ceramic), and K (Metal Can) Packages Are Now Obsolete.Download Complete Datasheet for Details.The LM329 temperature compensated 6.9 Volt Zener references provide excellent stability over time and temperature, very low dynamic impedance and a wide operating current range. The device achieves low dynamic impedance by incorporating a high gain shunt regulator around the Zener. The excellent noise performance of the device is achieved by using a "buried Zener" design which eliminates surface noise phenomenon associated with ordinary Zeners. To serve a wide variety of applications, the LM129 is available in several temperature coefficient grades and two package styles. A 20mA positive current source application is shown below.ApplicationsTransducersA/D and D/A ConvertersCalibration StandardsInstrumentation Reference
