LA4905 Description
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 ponents 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...
LA4905 Key Features
- Power dissipation reduced by 50% (When average music power is measured, and when pared to earlier Sanyo products.)
- The number of required signal follower circuits has been reduced to a single circuit for two channels, allowing the numb
- The output is a pure analog signal: no switching noise is output to the output lines
- Operates on an 8 to 18-V single-voltage power supply
- Full plement of built-in protection circuits (shorting to the power supply, shorting to ground, overvoltage, and thermal
- Built-in standby switch
