LM1112 Datasheet PDF - National Semiconductor Dolby B-Type Noise Reduction Processor Specs

LM1112 - Dolby B-Type Noise Reduction Processor

Datasheet Summary

Description

The LM1112 is a monolithic integrated circuit specifically designed to realize the Dolby B-type noise reduction system It is a replacement for the LM1111 and the Signetics NE645 648 but with improved performance figures

Features

Y Very high signal noise ratio 74 dB encode (CCIR ARM) Y Wide supply voltage range 6V to 20V Y Very close matching to standard Dolby characteristics Y Audible switch-on transients greatly reduced Y Improved temperature performance Y Reduced number of precision external components Y Improved transient stability Y Input protection diodes Available only to licensees of Dolby Laboratories Licensing Corporation San Francisco from whom licensing and.
