Monolithic Linear IC
LA4500
5.3W 2-Channel AF Power Amplifier
Features
• Low idling current (20mA/2 channels) enabling prolonged
battery life.
• Less dependence of idling current on VCC.
• High power (5.3W typ. ×2).
• High ripple rejection (60dB at steady state).
Since filters are arranged in 3 stages (including 1 stage
inside the IC) to attain satisfactory ripple rejection at tran-
sient state, ripple occuring at the time of motor start can
be prevented from mixing in.
• Low pop noise at the time of power supply ON/OFF and
good starting balance between both channels (0.6s.) due
to built-in pop noise limiter.
• Pins provided for compensating high frequency responce.
• Low residual noise (0.4mV).
• Wide supply voltage range (6 to 24V) fascilitating design
of transformer power supply.
• Built-in thermal shutdown circuit,
• Designed so that inverse insertion or short between adja-
cent pins causes no destruction.
• Channel-to channel mirror image pin assignment and pro-
vision of Pre GND, Power GND pins enabling stable op-
eration and fascilitating artwork of printed circuit board.
• Minimum number of external parts required (9pcs. min.,
12pcs. typ.).
• Audio muting capability (for automatic music selection,
electronic tuner).

(h) Feedback resistance RNF is contained and the voltage gain is fixed at 50dB so that the variations in the voltage
gain can be minimized. The gain can be lowered by connecting RNF externally.
(i) Biasing pin (12) as shown below causes DC audio muting to be applied, thereby cutting off the IC. This makes
attack time, recovery time, pop noise, etc. saticefactory.
It is recommended that the following method be used to control the NF pin.
It is recommended that the following method be used to control the NF pin.
