Ordering number : EN5504 Monolithic Linear IC LA4905 17-W, 2-Channel BTL AF High-Efficiency Power Amplifier for Car Stereo Systems Overview The LA4905 is a BTL 2-channel power amplifier IC for use in car audio systems.
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 newlydeveloped 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.
This contributes significantly to miniaturization of the heat sink and ...
