The audio amplifier circuit
is designed in bridge (BTL) mode configuration and will provide a
maximum output power of 20 watts on a 4 ohms load. The maximum output
power can be obtained using a 2 ohms load , in this case output power
will be around 26 watts . Also you can use a 8 ohms load , but in this
case , output power will be around 12 watts.
Note:
- Use 12V - 15V DC for powering the circuit.
- Fit the TDA724 IC to a proper heatsink.
