stereo-amplifier-ic-TDA1554-22W- 22W

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.

22W Power Amplifier with TDA1554 circuit diagram

Powered with main power IC TDA1554,  this circuit works up to 22W. A few externel components required to support the main component. Heatsink on the power IC is a must.

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 (For Input)

The? works best with 4 ohm speakers, but 8 ohm units will do. Thiscircuitdissipates roughly 28 watts of heat, so a good heatsink is necessary. The chip should run cool enough to touch with the proper heatsink installed.
Operated at 12 Volts and at about 5 Amps at full volume. Lower volumes use less current, and therefore produce less heat. Printed circuit board is preferred, but universal solder or perf board will do. Keep lead length short.
