TECHNICAL DATA
KIA6282K
BIPOLAR LINEAR INTEGRATED CIRCUIT
4.6W DUAL AUDIO POWER AMPLIFIER
KIA6282K is an audio power IC with built-in two channels
developed for portable radio cassette tape recorder with power
ON/OFF switch. Because of the parts reduction and SIP
(Single Inline Package), space merit is remarkable.
Thermal shut down protection circuit is built in.

4. OSCILLATION PREVENTIVE MEASURES
For oscillation preventive capacitor C6 and C7 between the output terminal and GND, it is recommended to use Polyester
film capacitor having good characteristics for temperature and for high frequency. Since the characteristics of the capacitor is
liable to be influenced the temperature, use this capacitor after the temperature test to check the oscillation allowance.
In addition, as the position of the electrolytic capacitor has a remarkable influence on the oscillation, connect C10 to VCC at the
nearest possible position from power GND. At using this application with the voltage gain reduced, oscillation is liable to be produced.
Apply the capacitor after checking enough for its capacity, type and mounting position.
* As the oscillation allowance varies according to the printed pattern layout, the standard printed board of KEC is recommended
to be referred to for design it.
5. POWER ON/OFF SWITCH
There is power ON/OFF switch at pin. However, output power is changed by pin supply voltage when
in not same pin supply voltage, after referring to attached date, select pin supply voltage.
pin supply voltage
6. INPUT VOLTAGE
When the excessive signal is input, turning-up is produced in the clip waveform.
The turning-up point is VIN=300mVrms(Typ.) : VCC=9V, RL=4 , f=1kHz : Enough care must be taken for this phenomenon.
7. GND LINE
GND pin is not separated for Pre-GND and for Pw-GND. That is liable to cause distortion and cross talk worse.
Before use this IC, please check it.
