Download the LM1112B datasheet PDF.
This datasheet also covers the LM1112 variant, as both devices belong to the same dolby b-type noise reduction processor family and are provided as variant models within a single manufacturer datasheet.
General 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
Key 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.
Note: The manufacturer provides a single datasheet file (LM1112_NationalSemiconductor.pdf) that lists specifications for multiple related part numbers.
