This circuit is a circuit-watt
amplifier size at a reasonable 22W 22W. This is the mod is perfect for listening at home or in any vehicle. Is a simple circuit. Use small pieces of equipment and an IC. Is only one number TDA1554Q. And within a short-circuit protection circuit with the output.
Principle of the circuit is.
Circuit to receive input on each channel C1 and C2. This will signal coupling or filter out specific signal only The left channel input signal as the right to work. So I explained just left alone. Signal to pass from C1 to the Pin 1 and pin 2 of IC1. This position will stand a horizontal leg inverter protest Amplifiers not to phase out the output pin 6. And the second leg is the leg position in a power amplifier to phase Ting. Out through the output pin 8. Which will be seen that output and second legs are legs 6 and Pin 8 are phase signals the opposite is to provide
power W increases itself. Power consumption power that job. to use up about 5 A at 12V. The speaker will use a 4 ohm speakers so the sound is currently 22 watt, but if it uses any 8 ohm speaker. But Watts will be lowered again. While working in the circuit will generate heat at the IC Therefore the disc cooled.
Components:
R1__________39K 1 / 4 watt
resistor, C1, C2_______10uf 25V electrolytic capacitor, C3__________100uf 25V electrolytic capacitor, C4__________47uf 25V electrolytic capacitor, C5__________0.1uf 25V ceramic capacitor, C6__________2200uf 25V electrolytic capacitor, U1__________TDA1554 Two Channel Audio Amp Chip, MISC________Heatsink For U1, Binding Posts (For Output), RCA jacks will (for input) This works best with 4 ohm speakers, 8 ohm operation, but do. This circuit has gone about 28 watts of heat, so that’s a good heatsink is required. The chip should run cool enough to touch the heatsink correctly installed.
Operated at 12 volts and about 5 amps at full volume. Small amounts consume less power and thus produce less heat. PCB is preferred, but universal solder or perf board will do. Keep lead length short.
