This electronic circuit project is a class AB audio power amplifier designed using the TDA7350 IC manufactured in a Multiwatt package .The TDA7350 audio power amplifier require few external components and can be used in stereo mode or mono (bridge ) mode . The TDA7350 audio power amplifier has many features like : high output power , no noise on on/off switch , programmable turn-on delay , ac-dc short circuit protections , overrating temperature protection and more . For this power amplifier we need to use a 4 ohms or 2 ohms speakers . If we use stereo configuration the output power is 11W on 2 ohms and 6.5W on 4 ohms with 10% distortion and if we use the bridge mode the output power is 20 W on 4 ohms speaker . For this power amplifier is need a dc power supply with a maximum output voltage of 18 volts ( the typical power supply needed by this power amplifier IC is 14.4 volts ) .
