CMOS LSI
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 â12 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
Package Dimensions

[LC7527E]
Features
⢠This LSI, in conjunction with a control microprocessor,
can implement in two chips, an electronic graphic
equalizer with the following features.
â One touch gain control for each band
â One touch memory setting recall allows users to
select desired frequency characteristics for each
track.
â Since the LC7527E includes band filter amplifiers
on chip, capacitors are the only external components
required in application systems.
â Minimal switching noise due to the use of a Silicon
gate CMOS process.

⢠CCB is SANYOâs original bus format and all the bus
addresses are controlled by SANYO.
