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

Circuit Description IC TA8210AH By using this you can apply a series of audio power amplifier is the car audio system. In general, all the speakers in the car using a subwoofer speaker, and woofer. Because the car is not big room so the sound is being required is not too high. Audio amplifier circuit can work at a minimum voltage 12-volt DC, if supplied under voltage 12-voltamplifier work will be less than the maximum. This amplifier output power up to 200W or 2 x 100W stereo with 8 ohm impedance.
