LC7527E

Graphic Equalizer System

Overview

The LC7527E is a microprocessor controllable seven-band

graphic equalizer LSI that does not require the use of

external semiconductor inductors (simulated inductors).

Functions

• Left and right channel seven-band graphic equalizers

• Each band operates in ±2 dB steps.

• Each band has a maximum boost of +12 dB and a

maximum cut of –12 dB for a total of 13 settings.

• Independent left and right channel operation

• Serial data input supports CCB format communications

with the system controller.

• CMOS LSI with a 12 V breakdown voltage

Features

• This LSI, in conjunction with a control microprocessor,

can implement in two chips, an electronic graphic

equalizer with the following features.

— One touch gain control for each band

— One touch memory setting recall allows users to

select desired frequency characteristics for each

track.

— Since the LC7527E includes band filter amplifiers

on chip, capacitors are the only external components

required in application systems.

— Minimal switching noise due to the use of a Silicon

gate CMOS process.

• CCB is a trademark of SANYO ELECTRIC CO., LTD.

• CCB is SANYO’s original bus format and all the bus

addresses are controlled by SANYO.
