Electronic Volume Control
for Car Stereo Systems
LC75373E
Overview
The LC75373E is an electronic volume control that can
implement volume, balance, fader, bass/treble + super
bass, loudness, input switching, and input/output level
control functions with a minimal number of external
components.
Functions
Volume: Provides 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 channels
independently.
Fader: This function can attenuate either the rear or the
front outputs over 16 positions. (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/treble: Forms an NF-type tone control circuit with
the addition of external capacitors. The base and treble
controls each have 15 positions.
Input gain: The input signal can be amplified from 0 dB
to +18.75 dB in 1.25 dB steps.
Output gain: One of two output of 0 dB and + 6.5 dB
can be selected for fader output.
Input switch: The signal can be selected from one of
four inputs for each of the left and right channels.
Super bass: The position of super bass can be controlled
in 11 steps.
Features
On-chip buffer amplifiers for a minimum of external
components.
Built-in reference voltage generation circuit
Serial data input: Supports CCB format communication
with the system controller.
