LC7527E Graphic Equalizer System

Ordering number : EN4466B 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). Package Dimensions unit: mm 3159-QFP64E [LC7527E] Functions • Left and right channel seven-band graphic equaliz.

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.
