FEATURES
DESCRIPTION
The LM1894 is a stereo noise reduction circuit for use
2
Non-Complementary Noise Reduction, “Single
with audio playback systems. The DNR system is
Ended”
non-complementary, meaning it does not require
Low Cost External Components, No Critical
encoded source material. The system is compatible
Matching
with
virtually
all
prerecorded
tapes
and
FM
broadcasts.
Psychoacoustic
masking,
and
an
Compatible with All Prerecorded Tapes and
adaptive bandwidth scheme allow the DNR to
FM
achieve 10 dB of noise reduction. DNR can save
10 dB Effective Tape Noise Reduction
circuit board space and cost because of the few
CCIR/ARM Weighted
additional components required.
Wide Supply Range, 4.5V to 18V
1 Vrms Input Overload
APPLICATIONS
Automotive Radio/Tape Players
Compact Portable Tape Players
Quality HI-FI Tape Systems
VCR Playback Noise Reduction
Video Disc Playback Noise Reduction
