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.
Features
.

.
Less pop noise
.
Designed for excellent sound quality
(fL < 10 Hz, fH = 130 kHz)
.
Any on time settable by external capacitor
.
Standby switch circuit on chip (microprocessor supported)
.
Various protectors on chip
(output-to-ground short/output-to-VCC short/
load short/overvoltage/thermal shutdown circuit)
.
NF capacitorless
.
Supports RL =2 Ω
