Monolithic Linear IC
LA4275
6.0 W AF Power Amplifier
for Home Stereo, TV Use
Features
. _{Small-sized package of 7-pin SIP}
. _{High power and low distortion}
P_O = 6.0 W at V_CC = 25 V, R_L = 8 Ω,
f = 1 kHz, THD = 1.0%
THD = 0.1% at V_CC = 25 V, R_L = 8 Ω,
. f = 1 kHz, PO = 2 W
Minimum number of external parts required (no bootstrap
capacitor required)
. _{Low pop noise at the time of power switch ON/OFF}
. _{Excellent ripple rejection (55 dB typ.)}
. _{Wide operating voltage range (10 V to 32 V)}
. _{Protector against abnormalities built in (thermal shutdown,}
overvoltage)
