Single-Chip Electronic Volume Control System

LC75395E

Overview

The LC75395E is an electronic volume control that

provides volume, balance, five-band equalization and

input switching functions. These functions are controlled

from serial input data.

Functions

• Volume control: The volume control provides 25

attenuation positions: from 0 dB to –17.5 dB in 1.25 dB

steps, from –17.5 dB to –25 dB in 2.5 dB steps, from

–25 dB to –36.25 dB in 3.75 dB steps and with settings

for –41.25 dB, –50 dB, –60 dB and –

∞.

A balance function can be implemented by controlling

the left and right channels independently.

• Equalizer: The equalizer function supports ±10 dB

control in 2 dB steps in each of the five bands. Of the

five bands, four provide peaking characteristics, and one

provides shelving characteristics.

• Selector: The selector function selects one of four inputs

for each of the left and right channels. An arbitrary

amplification level can be set for each input signal using

external components.

• Serial data input: All controls can be set from serial

input data (CCB format)

Features

• On-chip buffer amplifiers to minimize the number of

external components

• Silicon-gate CMOS process for minimal switching noise
