LMC1983  
Digitally-Controlled Stereo Tone and Volume Circuit with  
Three Selectable Stereo Inputs  
n Three pairs of stereo inputs  
n Loudness compensation  
n 40 position 2 dB/step volume attenuator plus mute  
n Independent left and right volume controls  
n Low noise-suitable for use with DNR® and Dolby® noise  
reduction  
General Description  
The LMC1983 is a monolithic integrated circuit that provides  
volume, balance, tone (bass and treble), loudness controls  
and selection between three pairs of stereo inputs. These  
functions are digitally controlled through a three-wire com-  
munication interface. There are two digital inputs for easy in-  
n External processor loop  
n Signal handling suitable for compact discs  
n Pop-free switching  
n Serially programmable: INTERMETAL bus (IM) interface  
n 6V to 12V single supply operation  
n 28 Pin DIP or PLCC Package  
terface to other audio peripherals such as stereo decoders.  
The LMC1983 is designed for line level input signals  
(300 mV–2V) and has a maximum gain of −0.5 dB. Volume  
is set at minimum and tone controls are flat when supply volt-  
age is first applied.  
Low noise and distortion result from using analog switches  
and poly-silicon resistor networks in the signal path.  
Additional tone control can be achieved using the LMC835  
stereo 7-band graphic equalizer connected to the  
LMC1983’s SELECT OUT/SELECT IN external processor  
loop.  
Applications  
n Stereo television  
n Music reproduction systems  
n Sound reinforcement systems  
n Electronic music (MIDI)  
n Personal computer audio control  
Features  
n Low noise and distortion
