Tda7294 Amplifier Circuit Diagram. Ic tda7294 100w dmos audio amplifier with mute option from st comes in multiwatt15v and multiwatt15h package. The working voltage is about 30v dual power supply.
Here below figure 18 is described a circuit proposal for a high efficiency amplifier which can be adopted for both hi fi and car radio applications. Ic tda7294 100w dmos audio amplifier with mute option from st comes in multiwatt15v and multiwatt15h package. This amplifier has four pieces of power ic tda7294.
Firstly it is used in hi fi field applications for amplification of audio signals which includes self powered loudspeakers tv etc.
Heat sink is required and its thermal resistance should be around 0 038 degree celsius watt. The tda7294 power amplifier is intended for the use of subwoofer speakers because the amplifier with the tda7294 chip is equipped with a subwoofer preamp there are also frequency and phase settings so we can add or reduce the output frequency as we wish and for the phase we can set from 0 180 level. The ic has a dmos output stage. For 100w output the supply voltage must be 38vdc.
