TDA7350 power amplifier circuit

This schematic circuit is a class AB audio power amplifier based on the TDA7350 IC designed in a Multiwatt  package .This TDA7350 power amplifier can be used for car radio applications and many other . The TDA7350 require few external components and can be used in stereo mode or mono (bridge ) mode .

If you want to make a simple power amplifier with very few external components required you can use this amplifier based on the TDA7350 .

The TDA7350 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 the TDA7350 power amplifier is need a dc power supply with a maximum output voltage of 18 volts ( the typical power supply needed by TDA7350 power amplifier is 14.4 volts ) .

As you can see in both circuits ( tda7350 bridge and stereo ) the schematic is almost the same , the major difference is that the pin 2 and 4 are connected each other in the bridge configuration .
