LM329BZ#PBF

LM329 is a temperature compensated 6.9V zener reference. It provide excellent stability over time and temperature, very low dynamic impedance and a wide operating current range. This 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, this device is available in several temperature coefficient grades and two package styles. It is used in application such as transducers, A/D and D/A converters, calibration standards, instrumentation reference etc.
