4.6W DUAL AUDIO POWER AMPLIFIER KIA6282
GENERAL DESCRIPTION
KIA6282 is an audio power IC with built-in two
Channels developed for portable radio cassette tape
recorder with power ON/OFF switch. Thermal shut
down protection circuit is built in. Because of the
parts reduction and SIP (Single in line package), space
merit is remarkable.

As the oscillation allowance varies according to the printed pattern layout, the
standard printed board is recommended to be referred to design it
5. INPUT VOLTAGE
When the excessive signal is input, turning-up is produced in the clip waveform.

care must be taken for this phenomenon.
6. POWER ON/OFF SWITCH
There is power ON/OFF switch at pin 3. However, output power is changed by pin
3 supply voltage when pin 3 voltage in not same pin 12 supply voltage, after
referring to attached date, select pin 3 supply voltage.
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.
