Ordering number: EN5245A Monolithic Linear IC LA4708 20 W 2-channel BTL AF Power Amplifier for Car Stereos Overview The LA4708 is a BTL two-channel power IC for car audio 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 LA4708 provides powerful bass and clear treble..

LA4708 Features

* on-chip protectors and standby switch. The LA4708 is also pin-compatible with the LA4705NA (car stereo-use 17 W two-channel power IC), and can be substituted for the LA4705NA for higher power. (When the board is shared, pins 1 and 9 must be left open.) Package Dimensions unit: mm 3109-SIP18H [LA47
