LM1894 Dynamic Noise Reduction System DNR

Check for Samples: LM1894

FEATURES

DESCRIPTION

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 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 required.
