TDA1554 audio amplifier circuits

The TDA1554 amplifier circuit can be used to stereo amplifier 22W and 4 Channel Home audio  11 watts using 11-15V power supply voltage  below we have 2 circuits

4 Channel Home Audio Amplifier 11 watt using TDA1554

This is a simple circuit. Just use a single IC, but the amplifier has 4 channels, 11 channels per watt, which is Philip TDA1554 number suitable for listening at home or in any vehicle. Just because the power supply 12-15 volt or will be used to expand any home theater sound system. The first 2-channel amplifier front speakers. And 2 to extend the back surround sound speakers also.

This circuit power supply 12 volts to 18 volts Power consumption at 5A. The input 4 input pins 1, 2, 17 and 18 is divided into a horizontal input inverter Ting 2 channels (Pin 1, 17). inverse model and input object 2 channels (pins 2, 6). That we can use that. To output phase to phase or did not return. The output will be the fourth slot on the leg 6, 8, 12, 10, with a C7-C10 serves to increase the low frequency stability better before you go to the speaker. The switch S1 acts on mute by pressing S1 will be closed sound system circuit in Mute, and if open circuit S1 standby ready to work. The C5 and C6 will filter light to smooth out and eliminate interference.


Stereo amplifier 22 watt by TDA1554

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.

These circuit below can be compatible with the above circuit.
