4 x 35 Watt car audio amplifier

Leave a Comment
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.

Description

The TDA7391 is a bridge class AB audio power amplifier specially intended for car radio high power applications. The high power capability together with the possibility to operate either in differential input mode or single ended input mode makes it suitable for boosters and high end car radio equipments. The exclusive fully complementary output stage and the internal fixed gain configuration drop the external component count.The on board clipping detector allows easy implementation of gain compression systems.

Description

The TDA7376B is a new technology dual bridge audio amplifier in Multiwatt 15 package designed for car radio applications. Thanks to the fully complementary PNP/NPN output stage configuration the TDA7376B delivers a rail-to-rail voltage swing with no need of bootstrap capacitors. Differential input pairs, that will accept either single ended or differential input signals, guarantee high noise immunity making the device suitable for both car radio and car boosters applications.The audio mute control, that attenuates the output  signal of the audio amplifiers, suppresses pop On - Off transients and cuts any noises coming  from previous stages. The standby control, that de-biases the amplifiers, reduces the cost of the power switch. The on-board programmable distortion detector allows compression facility whenever the amplifier is over driven, so limiting the distortion at any levels inside the presettable range.

200 Watt Stereo Car Amplifier

5 comments

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.
