LM1894N Description

Short technical summary and product information.

The LM1894N is a bipolar integrated circuit designed for stereo noise reduction in audio playback systems. Its DNR (Dynamic Noise Reduction) system is non-complementary, meaning it does not require specially encoded source material and is compatible with most prerecorded tapes and FM broadcasts.

 

The LM1894N achieves up to 10 dB of noise reduction through psychoacoustic masking and an adaptive bandwidth scheme. This allows for significant noise reduction without compromising audio quality. The circuit requires few external components, saving board space and cost.

 

Key features include a wide supply voltage range from 4.5V to 18V and a 1 Vrms input overload capability. The LM1894N is suitable for applications such as automotive radio/tape players, compact portable tape players, HI-FI tape systems, VCR playback, and video disc playback.

 

This component is available in a 14-PDIP through-hole package.
