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.
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.
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.
