特性 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 transient 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 adjacent pins

causes no destruction.

• Channel-to channel mirror image pin assignment and provision of Pre GND,

Power GND pins enabling stable operation 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).
