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.
