KIA6220H
BIPOLAR LINEAR INTEGRATED CIRCUIT
30W BTL DUAL AUDIO POWER AMPLIFIER.
The thermal resistance 6 j-c of KIA6220H 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.
It also contains output short detection circuit,
output clip detection and various kind of protection.

CAUTIONS AND APPLICATION METHOD
(Description is made only on the single channel.)
1. Voltage Gain Adjustment
Amp 1 :Pre—Amp
Amp2:Phase Amp
Amp3:Power Amp (Flat—Amp)
Amp4:Power Amp (Flat—Amp)
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 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 remarkable 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 Gyl.
R1 + (RF + R2)
Gyl=20Log
RF + R2
dB
1
The closed loop voltage gain of POWER Amp, Amp3 and Amp 4 is fixed at Gv3^Gv4=20dB.
Therefore, the total closed circuit voltage gain Gv is obtained through BTL
connection by the expression below.
Gv=Gyl+Gv3+6(dB)
