Monolithic Linear IC
LA4270
6W Dual-Channel AF Power Amplifier
Features
• High-output dual-channel AF Power IC.
(PO=6.0W×2, VCC=25V, RL=8Ω, f=1kHz, THD=1.0%)
• Low distortion (THD=0.1%, VCC=25V, RL=8Ω, f=1kHz,
PO=2W).
• Minimum number of external parts requierd (no boot-
strap capacitor requierd).
• Low pop noise at the time of power switch ON/OFF.
• High ripple rejection (58dB typ).
• Wide supply voltage range (10V to 32V).
• On-chip protector against abnormality (thermal shutdown,
overvoltage).

LA4270
In this application, output capacitors must be used. Since the IC handles an apparent load of 4Ω, more distortion results,
making it impossible for the IC to deliver power at THD=1% as in 2-channel use. It is possible for the IC to deliver
power at THD=5% or 10%
