Circuit Notes:

  • Power supply voltage should not exceed 40V.
  • Use stable and regulated power supply. The power supply should be has  minimum current output  2A.
  • Use heatsink to prevent overheating on the power IC.

About TDA7295:

The TDA7295 is a monolithic integrated circuit in Multiwatt15 package, intended for use as audio class AB amplifier in Hi-Fi field applications such as home theatre and topclass TV. The wide voltage range and to the high out current capability make the TDA7295 able to supply the highest power into both 4W and 8W loads even in presence of poor supply regulation, with high Supply Voltage Rejection.

The built in muting function with turn on delay simplifies the remote operation avoiding switching on-off noises.

Use Minimum 2A center tap transformer for maximum result for mono/single channel application. Change the capacitor with higher value (about 6800 uF). Recommended supply voltage is 40V.
