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.

CAUTIONS AND APPLICATION METHOD
(Description is made only on the single channel.)
1. Voltage Gain Adjustment
Amp 2 : Phase Amp Amp 4 : POWER Amp (Flat-Amp)
(Fig. 1)
This IC has the amplifier construction as shown in Fig.l. The Pre-Amp(Amp 1) is
provided to the primary stage, and the input voltage is amplified by the Flat Amps,
Amp 3 and Amp 4 of each channel through the phase Amp (Amp 2).
Since the input offset is prevented by Pre-Amp when Vcc is set to ON, this circuit
can remarkably reduce the pop noise.
The total closed loop gain Gv of this IC can be obtained by expression below when
the closed loop voltage gain of Amp 1 is Gvi.
RI+(RF+R2)
Gvi=201og
RF+R2
(dB)
(1)
The closed loop voltage gain of POWER Amp (Amp 3 and 4) is fixed at
Gv3^Gv4=20dB
Therefore the total closed loop voltage Gv is obtained through BTL connection by the expression
below.
Gv=Gvi+Gv3+6(dB)
(2)
For example, when Rf=0Q, Gv is obtained by the
expression (1) and (2) as shown below.
Gy N 24+20+6+=50dB
