TECHNICAL DATA
KIA6216H
BIPOLAR LINEAR INTEGRATED CIRCUIT
15W BTLX2CH AUDIO POWER AMPLIFIER
The thermal resistance 0]~T of KIA6216H package
designed for low thermal resistance, has a 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.
In addition, the functions of stand-by and muting,
and a variety of protection circuits are involved.
FEATURES
* Low Thermal Resistance.
: 0j-T=1.5°C/W (Infinite heat sink)
* High Power.
: POUT(1)=18W(Typ.)/Channel
(VCc=14.4V, f=lkHz, THD=10%, RL=4£)
: POUT(2)=15W(Typ.)/Channel
(Vcc=13.2V, f=lkHz, THD=10%, RL=4£)
* Low Distortion.
: THD=0.04%(Typ.)
(Vcc=13.2V, f=lkHz, POUT=1W, RL=4£, Gv=50dB)
* Low Noise.
: VNo=0.30mVrms (Typ.)
(Vcc=13.2V, RL=4£, Gv=50dB, Rg=0£, BW=20Hz~ 20kHz)
* Built-in stand-by function.
(With ® pin set at Low, power is turned OFF.)
: IsB=lj[/A(Typ.)
* Built-in muting function.
(With (D pin set at Low, power is turned OFF.)
: V(Mute)=IV(Typ.)
* Built-in various protection circuits.
: Thermal shut down, over voltage, OUT—>Vcc short,
OUT-GND short and OUT-OUT short.
* Operating supply voltage : Vcc=9~18V.

^-Advantage of Stand-by SW^-
(1) Since Vcc can directly be controlled to ON/OFF by the microcomputer, the switching
relay can be omitted.
(2) Since the control current is microscopic, the switching relay of small current
capacity is satisfactory for switching.
