Overview
The LC75412E and 75412W 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 dB in 1-dB steps, and –
∞ (81
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: Each band can be controlled in 2-dB steps
from ±0 dB to ±18 dB.
Input gain: 0 dB to +18.75 dB (1.25-dB steps)
amplification is possible for the input signal.
Input switching: Six input signals can be selected for
Left and for Right (five are single-
ended inputs and one is a differential
input.)
Loudness: A tap is output from the –32 dB position of a
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)
