Ordering number : ENA1783A LA4708N Monolithic Linear IC 20W 2-channel BTL AF Power Amplifier for Car Stereo http://onsemi.com Overview The LA4708N 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 capacitor-less circuit, and crosstalk which causes “muddy” sound has been reduced by improving both circuit and pattern layout. As a result, the LA4708N provides powerful bas.
