LA4905 17-W / 2-Channel BTL AF High-Efficiency Power Amplifier for Car Stereo Systems

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 pow.

LA4905 Features

* Power dissipation reduced by 50% (When average music power is measured, and when compared to earlier Sanyo products.)

* The number of required signal follower circuits has been reduced to a single circuit for two channels, allowing the number of external components to be reduced.
