LM832 - LM832 Dynamic Noise Reduction System DNR

Download the LM832 datasheet PDF. This datasheet also covers the LM8 variant, as both devices belong to the same lm832 dynamic noise reduction system dnr family and are provided as variant models within a single manufacturer datasheet.

General Description

The LM832 is a stereo noise reduction circuit for use with audio playback systems The DNR system is noncomplementary meaning it does not require encoded source material The system is compatible with virtually all prerecorded tapes and FM broadcasts Psychoacoustic masking and an adaptive bandwidth sc
