Ordering number : EN4881A CMOS LSI LC75382E Electronic Tone Controls for Car Stereo Systems Overview The LC75382E is an electronic tone control IC that can implement, with minimal external components, the complete range of tone and volume controls required in a car stereo, including volume, balance, fader, bass and treble, input switching and input level c.
• Volume:
Controls the left and right volume levels
independently from 0 dB to
–78 dB (in
2 dB steps) and
–∞ dB (41 settings).
Since the left and right levels are
independent this circuit also functions as
a balance control.
• Fader:
Attenuates either the rear or front outputs
over 16 levels, from 0 dB to
–20 dB in
2 dB steps, from
–20 dB to
–25 dB in
5 dB step, from
–25 dB to
–45 dB in
10 dB steps and then to
–60 dB and
–∞ dB.
• Bass/treble: Implements 21 position bass and treble
controls with the addition of external
capacitors.
• Input selector: Selects one of four inputs f.
