Monolithic Linear IC  
Audio Output for TV application  
LA4917H  
High-Effciency Two-Channel 7W BTL  
Power Amplifier ICs  
Overview  
The LA4917H is a high-effciency two-channel 7W BTL power amplifier IC. Increases in the number of external  
components are held to a minimum by adopting both a signal-following type switching scheme in the amplifier’s output  
stage power supply, and a nonlinear amplifier that has nonlinear characteristics in the signal system. The power dissipation  
(thermal loss) in the actual operating range has been reduced to about 1/2 that of earlier class B amplifier ICs.  
When used with the DIP-28H package, the IC dispenses with the heat sink and significantly contributes to space saving in  
the end product case.  
Features  
• High-efficiency two-channel 7W BTL power amplifier IC (V  
• Encapsulated in a DIP-28H package (heat sink free)  
= 12V, R = 8Ω)  
L
CC  
• Requires only one signal-following type switching circuit, contributing to a reduction in the number of external  
components  
• Provides analog outputs that generate no switching noise on the output lines  
• Built-in standby switches  
• Built-in protection circuits (overvoltage and thermal protection circuits)
