Overview
The LC75411ES and 75411WS are electronic volume
controllers that enable control of volume, balance, fader,
bass/treble, loudness, input switching, and input gain
using only a small number of external components.
Functions
Volume: 0 dB to –79.5 dB in 0.5-dB steps, and –
∞ (161
positions) Balance function with separate L/R
control
Fader: rear output or front output can be attenuated
across 16 positions (in 1-dB steps from 0 dB to
–2 dB, 2-dB steps from –2 dB to 20 dB, 10-dB
steps from –20 dB to –30 dB, and –45 dB,
–60 dB, –
∞)
Bass/treble: Both bass and treble can be controlled in
1-dB steps from 0 dB to ±6 dB, and in 2-dB
steps from ±8 dB to ±12 dB.
Input gain: 0 dB to +18.75 dB (1.25-dB steps)
amplification is possible for the input signal.
Input switching: four input signals can be selected for
Left and for Right
Loudness: A tap is output from the –32 dB position of a
2 dB step volume control resistor ladder.
A loudness function can be implemented by
connecting an external RC circuit.
Features
On-chip buffer amplifier cuts down number of external
components
Low switching noise generated by on-chip switch
through use of silicon gate CMOS process, for low
switching noise when there is no signal
Low switching noise when there is a signal due to use
of on-chip zero-cross switching circuit
On-chip 1/2 VDD reference voltage circuit
Controls performed with serial input (CCB)
