TECHNICAL DATA
BIPOLAR LINEAR Th'TEGRATED CIRCUIT
22W BTL DUAL AUDIO POWEH AMPLlFIEH
The thermal resistance f3.i -'1' KIA6210All package
CPP-17(Compact Power Package 17pin), designed for low
oB
thermal resistance, has high eHiciency 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
diIIerence between Land H channels.
In addition, the functions of stand-by and muting, and
a variety of protection circuits are involved.

This IC has Lhe amplifier consLrucLion as shown in Pig.1. The Pre- Amp(Amp 1) is
provided Lo Lhe primary sLage, and Lhe inpuL volLage is amplified by Lhe PIaL Amps,
Amp 3 and Amp 4 of each channel Lhrough Lhe phase Amp (Amp 2).
Since Lhe inpuL offseL is prevenLed by Pre- Amp Vcc is seL Lo ON, Lhis circuiL
can remarkably reduce Lhe pop noise.
The LoLal closed loop gain Cv of Lhis IC can be obLained by expression below when
Lhe closed loop volLage gain of Amp I is Cv1.
G V1 = 20]og RI +Rr(R+rR+2R2) (dB) .................. 0)
The closed loop volLage gain of POWER Amp (Amp 3 and 4) is fixed aL
Therefore, Lhe LoLal closed circuiL volLage gain Cv is obLained Lhrough HTL connecLion by Lhe expression
below.
CV=C V1 +Cv3+{)(dH) .................. (2)
Por example, when Rf=O Q, Cv is obLained by Lhe expression (1) and (2) as shown below.
