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 controls.
Features
• 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 for both the
left and right channels. The selected
input signal can be amplified by between
0 dB and +18 dB in 6 dB steps.
• The provision of on-chip operational amplifiers means
that few external components are required.
• Fabricated in a silicon gate process for minimal
switching noise.
• All functions can be controlled by serial data over a
CCB interface.
