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).
