Tda7294 Ic Circuit Diagram
The TDA7294 IC is a popular sound amplifier IC with low cost that has a ton of power handling capacity, 100W to be exact. For this tutorial, we are going to use two of those TDA7294 ICs in a bridge configuration to build an even more powerful amp that can handle up to 170W of RMS power. By circuit diagram 3 Comments This is the 300W RMS stereo power amplifier circuit project. This amplifier is based four pieces of power IC TDA7294. It's mean that every single channel of the circuit uses two ICs in bridge mode. In this application, the load value must not be less than 8 Ohms. The main advantages of this solution are the following: The OCL circuit diagram is shown in Figure 1. This circuit is a dual-channel 70W power amplifier composed of two TDA7294. There are few external components and simple circuit. When the power supply voltage is ±35V, 70W continuous output power can be obtained on an 8 ohm load. TDA7294 is an integrated, monolithic, Class AB audio amplifier designed specifically for Hi-Fi applications. The IC has a DMOS output stage and can deliver 100W RMS into an 8Ohm speaker at +/-38V dual supply. The TDA7294 has low noise, low distortion, good ripple rejection and can be operated from a wide range of supply voltages.
