Description

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.

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.
