Monolithic Linear IC  
LA4906  
17-W, 2-Channel BTL AF High-Efficiency  
Power Amplifier for Car Audio Systems  
Preliminary  
Overview  
• Uses a single-voltage power supply from 8 to 18 V.  
• Provides a full range of built-in protection circuits,  
The LA4906 is a BTL two-channel power amplifier for  
use in car audio systems. It uses a signal-following  
switching technique in the power supply for the amplifier  
output stage and a newly-developed nonlinear amplifier  
that features nonlinear characteristics in the signal system.  
These features hold increases in the number of external  
components to a minimum, and reduce power dissipation  
(and thus heat generation) in the practical operating region  
to about 1/2 that of earlier class B amplifier ICs. This can  
contribute significantly to miniaturization and weight  
reduction in the heat sink and to reduction of the heat  
generated within the end product case.  
including shorting of output pin to V , shorting of  
output pin to ground, overvoltage, and thermal  
shutdown protection.  
• Built-in standby switch  
• Clipping detection function

[LA4906]  
Features  
• Power dissipation reduced by 50% (for music at average  
power levels, as compared to earlier Sanyo products)  
• The number of required signal-following switching  
circuits has been reduced to just one circuit for two  
channels, reducing the number of external components.  
• The output is a pure analog signal; no switching noise  
whatsoever appears on the output lines.

Notes: 1. Set VCC and RL to be in the range where Pd max does not exceed 37.5 W.  
2. The overvoltage protection circuit operates at VCC = 26 V or higher.
