My Light Diagram

This amplifier circuit based on the ic, and the use here is that where ic STK4017 IC has output power of 6.5 watts with the impedance 8Ohm. Minimum required supply voltage and maximum 20Volt 35 Volt DC. Component R1 = 100K R2 = 2K7 R3 = 27R C1 = 22uF C2 = 100uF C3 = 100uF C4 = 100uF C5 = 100uF C6 = 47uF C7 = 330uF C8 = 100uF U1 = STK4017 Besides using STK4017 ic, ic and can use that I mentioned the following: STK4019 STK4021 STK4023 STK4025

This general-purpose low-power (5 W) audio amplifier is suitable for driving a spaker 5W Audio Amplifier With Ac Power Supply Circuit Diagram of approximately 8 to 12 inches. A Sanyo LA4460 IC is used as the audio output IC. The circuit consists of a loudness control, driver amplifier Ql, and bass and treble controls of about ±10 dB boost/cut. It should be useful in a wide variety of situations. Either the ac supply shown can be used, or a 12 Vdc supply can be connected to points A&B (positive) and C (negative). Two of these circuits, using ganged potentiometers at R2, R7, and Rll can be used for stereo applications. T1 is a 12-V 1-amp plug-in transformer. Notice that IC1 must be heatsinked. Power output is about 5 W. A 4` 2` 0.050` aluminum heatsink should be adequate .
