CMOS LSI
LC75371M
Car Stereo Electronic Tone
and Volume Control
Overview
The LC75371M is an electronic tone/volume control LSI
that can implement, with minimal external components,
volume, balance, fader, bass and treble, loudness, input
switching, and input level controls.
Functions
• Volume control: From 0 to –79 dB in 1-dB steps plus
–∞ for a total of 81 settings. Since the left and right
levels can be set independently, this function can also be
used to implement a balance function.
• Fader: Attenuates either the rear or front channels to
one of 16 levels. (Provides 16 settings, namely, from 0
to –20 dB in 2-dB steps, from –20 to –25 dB in one
5-dB step, from –25 to –45 dB in 10-dB steps, –60 dB,
and –∞.)
• Bass and treble controls: Forms an NF-type tone control
circuit (LUX type) using external capacitors. Provides
15 settings each for the bass and treble controls.
• Loudness control: A loudness function can be
implemented by attaching external RC circuits at the
taps provided from the volume control resistor ladder
starting at the –20-dB position.
• The input signal can be selected from one of three inputs
for each of the left and right channels. The input signal
can be amplified by between 0 and +18 dB in 6-dB steps.
• Serial data input: Supports CCB* format communication
with the system controller.
