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.

Features
鈥?Volume: 0 dB to 鈥?9 dB (in 1 dB steps) and 鈥撯垶;
81 positions.
A balance function can be implemented using the
LC75383E independent left and right volume control
functions.
鈥?Fader: The rear channels or the front channels can be
attenuated over 16 positions: from 0 dB to 鈥?0 dB in
2 dB steps, from 鈥?0 dB to 鈥?5 dB in one 5 dB step,
from 鈥?5 dB to 鈥?5 dB in 10 dB steps, 鈥?0 dB, and 鈥撯垶
for a total of 16 positions.
鈥?Bass/treble: The LC75383E supports 21 position bass
and treble controls using external capacitors.
鈥?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.
鈥?Built-in operational amplifiers mean that few external
components are required.
鈥?Silicon gate process for minimal switching noise.
鈥?All controls can be set from serial input data (CCB).
鈥?CCB is a trademark of SANYO ELECTRIC CO., LTD.
鈥?CCB is SANYO鈥檚 original bus format and all the bus
addresses are controlled by SANYO.
