LC75386NE

Electronic Volume and Tone Control

for Car Stereo Systems

Overview

The LC75386NE is an electronic volume and tone control

IC that can implement a wide range of functions including

volume, balance, fader, bass and treble controls, loudness,

input switching, and input gain control with a minimal

number of external components.

Functions

• Volume:

0 to –79 dB ( in 1-dB steps) and –∞ for

a total of 81 settings.

A balance function can be implemented

by controlling the left and right channel

volume settings independently.

• Fader:

The rear or the front outputs can be

attenuated over 16 settings.

(0 to –2 dB in 1-dB steps, –2 to –20 dB

in 2 dB steps, –20 to –30 dB in 10-dB

steps, –45 dB, -60 dB, and –∞ for a

total of 16 settings.)

• Bass and treble: Control over a ±12-dB range in 2-dB

steps in each band.

• Input gain: The input signal can be amplified from

0 to +18.75 dB (in 1.25-dB steps).

• Input switching: One of 6 inputs can be selected for

each of the left and right channels.

(Five are single-ended inputs, and one

is a differential input.)

• Loudness:

Taps are output from the –32-dB

positions of the 2-dB step volume

ladder resistors, and loudness operation

can be implemented by attaching

external capacitors.

Features

• On-chip buffer amplifiers minimize the number of

external components required.

• The low level of switching noise generated from internal

switches due to fabrication in a CMOS process

minimizes switching noise when no input signals are

present.

• The use of built-in zero-cross switching circuits

minimizes switching noise when input signals are

present.

• Built-in VDD/2 reference voltage generation circuit

• All controls are controlled from CCB serial data input.
