CMOS IC
LC75384NE-R, 75384NW
Electronic Volume and Tone Control
for Car Stereo Systems
Overview
The LC75384NE-R and LC75384NW are electronic
volume and tone control ICs that can implement volume,
balance, fader, bass/treble/mid, loudness, input switching,
and input gain control functions with a minimum number
of external components.
Features
• Volume: 81 positions: from 0 dB to –79 dB in 1-dB steps
and –∞.
A balance function can be implemented by
controlling the left and right volume settings
independently.
• Fader: Either the rear or front outputs can be attenuated
over 16 positions. (16 positions: From 0 dB to
–2 dB in 1-dB steps, from –2 dB to –20 dB in
2-dB steps, from –20 to –30 dB in one 10-dB step,
–45 dB, –60 dB, and –∞.)
• Bass/treble/mid: Control over ±12 dB in 2-dB steps in
each band.
• Input gain: The input signal can be amplified by from
0 dB to +18.75 dB in 1.25-dB steps.
• Input switching: The left and right channels can each be
selected from one of 5 inputs. (Four are
single-ended inputs and one is a
differential input.)
• Loudness: Taps are output from a 2-dB step volume
control ladder resistor starting at the –32-dB
position. A loudness function can be
implemented by attaching external capacitors
and resistors.
• On-chip buffer amplifiers minimize the number of
required external components.
• Minimal switching noise when no input signals are
present due to fabrication in a silicon gate CMOS
process that minimizes the noise generated by internal
switches.
• Use of zero-cross switching circuits for internal switches
minimizes switching noise when signals are present.
• Built-in VDD/2 reference voltage generator circuit
• All controls can be set from serial input data.

• CCB is SANYO’s original bus format and all the bus
addresses are controlled by SANYO.
