25 Watt mono BTL class-D audio amplifier demonstration board based on the TDA7491MV
  • active Active

The STEVAL-CCA043V1 demonstration board is designed for the TDA7491MV mono BTL class-D power amplifier.

Thanks to its high efficiency, the device assembled in the PSSO36 (slug-down) package is capable of dissipating heat without a heatsink.

Jumpers on the board allow the configuration of the amplifier in order to verify all the features as single-ended or differential input, fixed gain settings.

Microswiches are also provided to enable the standby and mute functions.
