1W Audio power amplifier circuit
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
Mini VCD/DVD
Walkman
Ipod/Ipad
Mp3, Mp4 player
etc.
