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
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).
