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).
