Amplifier circuit using ic STK4065 above that which the amplifier circuit uses only ic, or also could be called this series do not have equality in the use of ic. Power amplifier output power 35Watt supplied with a voltage of 13.5 volts DC. Impedance of the output is 8 ohms. that can be applied to the speaker subwoofer, woofer, and fullrange. Component list : R1 = 2,2R R2 = 2,2R C1 = 1uF C2 = 100uF C3 = 100uF C4 = 220uF C5 = 470uF C6 = 0.47uF C7 = 220uF C8 = 33pF C9 = 220uF C10 = 33pF C11 = 0.47uF U1 = STK4065

This is the Digital ICs Drive Amplifier Circuit Diagram . Digital ICs and opto-isolators provide the drive for this TMOS servo amplifier, resulting in fewer analog circuits and less drift. Fast and consistent turn-on and turn-off characteristics also enable accurate analog output results directly from the digital signal without the need for analog feedback.  Digital ICs Drive Amplifier Circuit Diagram An `H` bridge configuration is employed for the servo amplifier, which obtains complementary PWM inputs from digital control circuits. The PWM inputs are applied via opto-isolators, which keep the digital control logic isolated from the 75 V supply used for the amplifier.
