Source: InternetPublisher:张小哥 Keywords: Application circuit TDA7294 BSP output power Updated: 2021/06/29
The power amplifier circuit using 294 groups has the characteristics of simple peripheral circuit and easy production. The input impedance of the circuit
is 20kfl, and the input sensitivity is 750rrN. This circuit can be used for either 8fl load or 40, load.
The output power under the two loads is the same.
Figure 2-74 is a 100W power amplifier circuit composed of TDA7294 , using ±40V voltage and an output power of 100W.
The supporting power supply should have sufficient capacity.
