LM1894 - Dynamic Noise Reduction System DNR

Download the LM1894 datasheet PDF. This datasheet also covers the LM1 variant, as both devices belong to the same dynamic noise reduction system dnr family and are provided as variant models within a single manufacturer datasheet.

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.

Features

  • n Non-complementary noise reduction, “single ended” n Low cost external components, no critical matching Typical.

LM1894 Dynamic Noise Reduction System DNR December 1994 LM1894 Dynamic Noise Reduction System DNR ® General 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. n Compatible with all prerecorded tapes and FM n 10 dB effective tape noise reduction CCIR/ARM weighted n Wide supply range, 4.
