LA4440
6W 2-Channel, Bridge 19W typ Power Amplifier
Features
• Built-in 2 channels (dual) enabling use in stereo and bridge
amplifier applications.
Dual : 6W×2 (typ.)
Bridge : 19W (typ.)
• Minimun number of external parts required.
• Small pop noise at the time of power supply ON/OFF and
good starting balance.
• Good ripple rejection : 46dB (typ.)
• Good channel separation.
• Small residual noise (Rg=0).
• Low distortion over a wide range from low frequencies to
high frequencies.
• Easy to design radiator fin.
• Built-in audio muting function.
• Built-in protectors.
a. Thermal protector
b. Overvoltage, surge voltage protector
c. Pin-to-pin short protector
