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
PO = 6.0 W at VCC = 25 V, RL = 8 Ω,
f = 1 kHz, THD = 1.0%
THD = 0.1% at VCC = 25 V, RL = 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)
