LM832 Dynamic Noise Reduction System DNR  
É
General Description  
Features  
Y
Low voltage battery operation  
The LM832 is a stereo noise reduction circuit for use with  
audio playback systems. The DNR system is noncomple-  
mentary, meaning it does not require encoded source mate-  
rial. The system is compatible with virtually all prerecorded  
tapes and FM broadcasts. Psychoacoustic masking, and an  
adaptive bandwidth scheme allow the DNR to achieve 10  
dB of noise reduction. DNR can save circuit board space  
and cost because of the few additional components re-  
quired.  
Y
Non-complementary noise reduction, ‘‘single ended’’  
Low cost external components, no critical matching  
Compatible with all prerecorded tapes and FM  
10 dB effective tape noise reduction CCIR/ARM

Wide supply range, 1.5V to 9V  
150 mVrms input overload  
No royalty requirements  
The LM832 is optimized for low voltage operation with input  
levels around 30 mVrms.  
Cascade connection for 17 dB noise reduction  
For higher input levels use the LM1894.  
Applications
