LC75383E

Ordering number : EN5002A CMOS LSI LC75383E Electronic Volume Control for Car Audio Systems Overview The LC75383E is an electronic volume control that provides volume, balance, fader, bass/treble, input switching and input level controls. The LC75383E supports all these functions while requiring a minimum number of external components. Package Dimensions unit: mm 3159-QFP64E [LC75383E] Features Volume: 0 dB to –79 dB (in 1 dB steps) and – ∞ ; 81 positions. A balance function can be implemented using the LC75383E independent left and right volume control functions. Fader: The rear channels or the front channels can be attenuated over 16 positions: from 0 dB to –20 dB in 2 dB steps, from –20 dB to –25 dB in one 5 dB step, from –25 dB to –45 dB in 10 dB steps, –60 dB, and –∞ for a total of 16 positions. Bass/treble: The LC75383E supports 21 position bass and treble controls using external capacitors. Input selector: The LC75383E can select one of four L/R inputs. The selected input signal can be amplified from 0 dB to +18 dB in 6 dB steps. Built-in operational amplifiers mean that few external components are required. Silicon gate process for minimal switching noise. All controls can be set from serial input data (CCB). CCB is a trademark of SANYO ELECTRIC CO., LTD.
