Overview
Ordering number: EN3848D Monolithic Linear IC LA4705 15 W 2-channel BTL AF Power Amplifier for Car Stereos Overview The LA4705 is a BTL two-channel power IC for car audio and radio-cassette players developed in pursuit of excellent sound 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.
