1W Audio power amplifier circuit

LA4145 an IC with SIL-9 package and manufactered by SANYO. This ic has miraculous equation with LA4146 and LA4147, so if you do not have the IC LA4145 but you have IC LA4146 or LA4147 , you still can make the above amplifier circuit. The circuit includes circuit of classes on low power because it has low output is 1W with 8 ohm impedance.
Technical information :
Min. Voltage = 6 Volts
Max. Voltage= 12 Volts
P. Out            = 1 Watt
RL                 = 8 Ohm
Ft                  = 40Hz - 17 Khz
Icco              = 10 mA

You can use to  :
Tuner/ Radio
Mp3, Mp4 player
