Digitally-controlled Stereo Tone And Volume Circuit With Three Selectable Stereo Inputs - National Semiconductor

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- terface to other Audio peripherals such as stereo decoders. The LMC1983 is designed for line level input signals (300 mV2V) 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 LMC1983s SELECT OUT/SELECT IN external processor loop. By National Semiconductor Corporation
