ZENER_GENERATOR

Published:2009/7/2 3:39:00 Author:May | From:SeekIC

Uses National LM389 array having three transistors along with opamp. Application of reverse voltage to emitter of one grounded-base transistor breaks it down in avalanche mode to give action of zener diode. Reverse voltage characteristic, typically7.1 V, is used as noise source for amplification by second transistor and power opamp. Third transistor(notshown) can be used to gate noise generator if desired.- Audio Handbook, National Semiconductor. Santa Clara. CA. 1977. p 4-33-4-37.
