Monolithic Linear IC  
LA4728  
2-Channel BTL Power Amplifier (35 W+35 W)  
with Standby Switch for Car Stereos  
Preliminary  
Overview  
Package Dimensions  
The LA4728 is a BTL two-channel power IC for car  
audios developed in pursuit of excellent sound quality.  
unit: mm  
3113A-SIP14HZ  
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 LA4728 provides powerful bass and clear treble.  
[LA4728]  
Features  
High power: supports total output of 35 W+35 W. [EIAJ  
power] (V =14.4 V, THD=30 %, R =4 )  
CC  
L
Less pop noise.  
Designed for excellent sound quality.  
(f <10 Hz, f =130 kHz)  
L
H
Any rise time settable by an external capacitor.  
Standby switch circuit on chip. (microcontroller support-  
ed)  
SANYO: SIP14HZ  
Various protectors on chip.  
(output-to-ground short/ output-to-V short/ load  
CC  
short/ overvoltage/ thermal shutdown circuit)  
The LA4728 is pin-compatible with the LA4725.
