LMC1983 Digitally-Controlled Stereo Tone and Volume Circuit with Three Selectable Stereo Inputs

The 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 communication interface. There are two digital inputs for easy interface 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 voltage 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. Three pairs of stereo inputs Loudness compensation 40 position 2 dB/step volume attenuator plus mute Independent left and right volume controls Low noise-suitable for use with DNR and Dolby noise reduction External processor loop Signal handling suitable for compact discs Pop-free switching Serially programmable: INTERMETAL bus (IM) interface to 12V single supply operation 28 Pin DIP or PLCC Package

Applications

Stereo television Music reproduction systems Sound reinforcement systems Electronic music (MIDI) Personal computer audio control

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the deivce may occur. Operating Ratings indicate conditions for which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics may degrade when the device is not operated under the listed test conditions. Note 2: All voltages are specified with respect to ground. Note 3: When the input voltage (VIN) at any pin exceeds the power supply voltages (VIN V- or VIN > V+) the absolute value of the current at that pin should be limited mA or less. The 20 mA package input current limits the number of pins that can exceed the power supply voltages with 5 mA current limit to four. Note 4: The maximum power dissipation must be derated at elevated temperatures and is dictated by TJMAX, JA, and the ambient temperature TA. The maximum allowable power dissipation PD = (TJMAX - TA)/JA or the number given in the Absolute Maximum Ratings, whichever is lower. For the LMC1983CIN, TJMAX = +125C, and the typical junction-to-ambient thermal resistance, when board mounted, is 67C/W.
