Stereo amplifier 3W + 3W using ic BA5406

IC number is BA5406 IC stereo audio amplifier size 3 watt + 3 watt.The circuit is small and easy to create.Suitable for expanding the use of music in a private room.Or may be used in any trial.
When raising the power supply 12 volts to this circuit.Input the left and the right to access the input pin, to pin 5 and pin 8 of IC.The signal through the C1 and C2 are coupling signal.To prevent DC, to interfere in the circuit.Then the amplifier IC is not a return phase.Exit output, Pin 2 and Pin 11.And the output signal out of each channel, left and right through C9 and C10.Add to block DC and low frequency stability.Then went out to the speakers.The C7 and C8 are connected to pins 3 and pin 10 of IC, respectively.The pin 3 and pin 10 is pin Boot Strap will help to gain a better.The C5 and C6 are connected to pins 6 and Pin 7.A pin Filter, the C5 and C6 serve cut noise from the IC.

Mini-stereo circuit using ic TDA2822

This circuit IC1 TDA2822 number as your primary device. The Dual Amplifier IC or IC stereo gain at 40 dB. Bandwidth 120 kHZ. That is about 2 watts and watt power supply of 1.8 to 15 volts and a current 6 mA only
When using the power supply 9 volt into this circuit.VR1 and VR2 to adjust the signal level of the right and left, the pin 7 and pin 6 of IC1.The amplifier IC1 is out of the output pin 1 and pin 3, through the C4 and C5 coupling signals to the left and right speakers.The C6, R1 and C7, R2 is to reduce noise.

Small audio amplifier IC 7w using lm383

This circuit, will help expand the sound small. such as radio, sound out, including CD WALKMAN. To the more powerful sound.The amplifier circuit can be up to 7 watts. Enough to use a good listening room.And most importantly is a very simple circuit.
Operation of the circuit. be Input signal is coupling with the C1.Passed into the pin 1 of IC1 number LM383. Amplifier output from the pin 4.Through C3 increase in low frequency stability better, before leaving to the speaker. The R2 and R3 set the gain 100 times. Which is calculated from the (R3/R4) +1.The C2 functions help in frequency response.
