LM1894, LM1 Datasheet - National Semiconductor

LM1894 Dynamic Noise Reduction System DNR

The LM1894 is a stereo noise reduction circuit for use with audio playback systems. The DNR system is non-complementary, 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 bandw.

LM1894 Features
