Description

The STEVAL-CCA028V1 demonstration board is

designed for the TDA7491P high-power dual BTL

class-D audio amplifier.

Thanks to its high efficiency, the device

assembled in the PSSO36 (slug-down) package

is capable of dissipating heat without any

heatsink.

Jumpers on the board allow configuring the

amplifier in order to verify all the features as

single-ended or differential inputs, fixed gain

settings.

Microswitches are also provided to enable the

standby and mute functions.
