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. In addition, the 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.)
