5 8 Watt audio power amplifier
This amplifier circuit has a power output of a small or too low at 5.8 Watt, which uses IC KA2205. The required voltage for at least 6 volts to 18 volts DC maximum.
Schematics power audio amplifier with IC KA2205
Component List
C1 = 1uF
C2 = 100uFC3 = 47uF
C4 = 1000uFC5 = 0.1uF
C6 = 220uF
IC1 = KA2205

TDA2822 made for 5 1 audio amplifier system
Skema Rangkaian Circuit combination of the 3 IC TDA2822 above can be used for 5.1 audio power amplifier system with low power output . The input signal used is analog signal not digital (SPDIF) , so it needed some input to the jack input. The speakers are suitable for use have impedance 8 Ohms , and with power 4 Watt, to Left , Right , Rear pair , center , and subwoofer speakers. To run this circuit , is also required circuit for volume control as tone control.
Component and technical Information :
C1-C6 : 220uF/25V
C7-C9 : 47uF/16 V
IC : TDA2822 x3
CON-1: VCC +12volts DC
CON-2: Ground
CON-3: Left Speaker
CON-4: Right Speaker
CON-5: Rear Speaker
CON-6: Rear Speaker
