Audio amplifier circuit is very suitable for use at home, using a subwoofer speaker, or woofer speaker. Usually, also called home amplifier, audio amplifiers are based on the IC and ic are used still in series with type STK457 STK and besides it also can use the STK459, 460, 461, 463, 465. And each ic has the quality of each one, please look at alldatasheet.com. Part List : R1 = 22K R2 = 22K R3 = 330R R4 = 33K R5 = 1K R6 = 1K R7 = 4.7R R8 = 3K3 R9 = 3K3 R10 = 4.7R R11 = 100R R12 = 33K R13 = 330R C1 = 0.1uF C2 = 0.1uF C3 = 100uF C4 = 100uF C5 = 0.1uF C6 = 47uF C7 = 47uF C8 = 0.1uF C9 = 100uF C10 = 100uF U1 = STK457,STK459, 460, 461, 463, 465.

Components of the above is one component of ic which is applied as a reinforcement. Power amplifier used in an audio signal in order to become more powerful and can be heard via a tool that is the speaker. But in each set must have a voice amplifier, voltage, power quality is different. For the IC has the output power above 2 X 40 Watt with 8 Ohm output impedance. Supply voltage ranging from 18 Volt to 32 Volt.

The STK402-900 series products are audio power amplifier hybrid ICs that consist of optimally-designed discrete component power amplifier circuits that have been miniaturized using SANYO's unique insulated metal substrate technology (IMST). The adoption of a newlydeveloped low thermal resistance substrate allows this product to integrate five power amplifier channels in a single compact package. 30 Watt x 5 Channels Audio Power Amplifier

General Description: The AN7560Z is an audio power IC developed as the sound output of car audio (35 W by 4-ch.). A capacitor and resisitor to stop oscillation are built in between the output pin and GND so that a space saving of set is possible. Also, it incorporates a perfect muting circuit with out shock noise so that a shock noise design under the set transient condition can be made easily when used together with its standby function. In addition, it incorporates various protection circuits to protect the IC from destruction by GND-open-shortcircuit to ground and power supply surge which are the important subject of power IC protection. This IC will largely contribute to a high reliability design of the equipment. Circuit Diagram: 4 x 35 Watt car audio amplifier Datasheet for AN7560:  Download
