Monolithic Linear IC

LA4705

15 W 2-channel BTL AF Power Amplifier

for Car Stereos

Overview

Package Dimensions

unit: mm

The LA4705 is a BTL two-channel power IC for car audio and

radio-cassette players developed in pursuit of excellent sound

3109-SIP18H

quality. Low-region frequency characteristics have been

improved through the use of a new NF capacitorless circuit,

and crosstalk which causes ‘‘muddy’’ sound has been reduced

by improving both circuit and pattern layout. As a result, the

LA4705 provides powerful bass and clear treble. In addition,

the LA4705 features on-chip protectors and standby switch.
