Monolithic Linear IC  
Four-Channel BTL Power  
Amplifier for Car Audio Systems  
LA47202P  
Overview  
The LA47202P is a 4-channel BTL power amplifier IC developed for use in car audio applications. The LA47202P adopts  
a pure complementary output stage circuit structure with a v-pnp transistor for the high side and an npn transistor for the  
low side to provide both high output power and high quality sound.  
The LA47202P integrates all the functions required for car audio applications on the same chip, including a standby switch,  
a muting function, and a full complement of protection circuits. It also features a self diagnostics function.  
Functions  
• High output : P max = 47W (typ.) (V  
= 14.4V, f = 1kHz, JEITA max, R = 4Ω)

: P max = 29W (typ.) (V

: P max = 22W (typ.) (V

• Muting function incorporated (pin 22)  
• Built-in standby switch (pin 4)  
• Self diagnostics function incorporated (pin 25) :  
Output of both output offset detection, shorting to V  
• Electric mirror noise decrease  
or ground and load shorting signals  
CC  
• Full compliment of protection circuits (shorting to V , shorting to ground, load shorting, overvoltage, and thermal  
CC  
protection).  
• Improved oscillation stability  
Note 1 : Take care to avoid wrong connection. Otherwise, IC or equipment may suffer breakdown, damage, or deterioration.  
Note 2 : The protective circuit function is to avoid the abnormal state (wrong connection of the output) temporarily and does  
not guarantee that IC is not broken.  
These protective functions do not operate outside the operation guarantee range, and wrong connection of output  
may cause breakdown of IC.  
Note 3 : External parts, such as the anti-oscillation part, diode to prevent breakdown, may become necessary depending on the  
set condition. Check their necessity for each set.  
Any and all SANYO Semiconductor products described or contained herein do not have specifications  
that can handle applications that require extremely high levels of reliability, such as life-support systems,  
aircraft's control systems, or other applications whose failure can be reasonably expected to result in  
serious physical and/or material damage. Consult with your SANYO Semiconductor representative  
nearest you before using any SANYO Semiconductor products described or contained herein in such  
applications.  
SANYO Semiconductor assumes no responsibility for equipment failures that result from using products  
at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition  
ranges, or other parameters) listed in products specifications of any and all SANYO Semiconductor
