Overview
The LC75394NE is an electronic volume control system
providing control over volume, balance, 5-band equalizer,
and input switching based on serial inputs.
Functions
Volume control:
The chip provides 25 levels of volume attenuation: in 2-
dB steps between 0 dB and –20 dB, 3-dB steps between
–20 dB and –32 dB, 4-dB steps between –32 dB and –52
dB, 4.5-dB steps between –52 dB and –70 dB, and –
.
Independent control over left and right channels
provides balance control.
Equalizer:
The chip provides control in 2-dB steps over the range
between +10 dB and –10 dB. Four of the five bands
have peaking equalization; the remaining one, shelving
equalization.
Selector:
The left and right channels each offer a choice of four
inputs. An external constant determines the
amplification for the input signal.
Features
Built-in buffer amplifiers reduce the number of external
parts necessary.
Silicon gate CMOS reduces switching noise.
Serial data input
—Supports CCB* format communication with the
system controller.
A built-in reference voltage circuit divides the supply
voltage (V
DD
) in half.
