TECHNICAL DATA
BIPOLAR LINEAR INTEGRATED CIRCUIT
30W BTL DUAL AUDIO POWER AMPLIFIER
The thermal resistance 0 j - c of KIA6221AH package
CPP-17 (Compact Power Package 17pin), designed for
low thermal resistance, has high efficiency of heat
radiation.
The temperature rise of chip can be reduced, and
the influence from the degradation of the features due
to the temperature rise at the high output can also be
reduced.
This stereo audio power IC, designed for car audio
use, has two built-in channels to reduce the
characteristic difference between L and R channels.
FEATURES
* Low Thermal Resistance
: 6 j-c=1.5°C/W (Infinite heat sink)
* High Power
:POUT( 1)=30W(Typ. )/Channel
(Vcc=14.4V, f=lkHz, THD=10%, RL=2&)
:POUT(2)=26W(Typ. )/Channel
(Vcc=13.2V, f=lkHz, THD=10%, RL=2&)
;POUT(3)=19W(Typ. )/Channel
(Vcc=13.2V, f=lkHz, THD=10%, RL=4&)
* Low Distortion
:THD=0.04%(Typ.) (VCc=13.2V, f=lkHz, POUT=1W, R l = 4 & , Gv=50dB)
* Low Noise
rms (Typ.)
(Vcc=13.2V, RL=4 Q, Gv=50dB, Rg=0&, BW=20Hz~ 20kHz)
* Built-in stand-by function (With @ pin set at LOW, Power is turned OFF.)
:IsB=ljuA(Typ.)
* Built-in various protection circuits
Protection circuits : thermal shut down, over voltage, Out—>Vcc short.
Out^GND short and OUT-OUT short.
* Operating supply voltage : Vcc=9~18V

For example, when Rf=0£2, Gv is obtained by the expression (1) and (2) as shown below.
Gv=24+20+6=50(dB)
The voltage gain is reduced when Rf is
increased. (Fig. 2)
With the voltage gain reduced, since (1)
the oscillation stability is reduced, and
(2) the pop noise changes when Vcc
is set to ON, refer to the items 3 and 4

2. Stand-by SW Function
By means of controlling @ pin (Stand-by terminal) to High and Low, the power
supply can be set to ON and OFF.
The threshold voltage of @ pin is set at about 3V(Typ.), and the power supply
current is about lM(Typ.) at the stand-by state.
Fig.3 With ( ? ) Pin set to High, Power is turned ON.
