Description

The STEVAL-CCA027V1 demonstration board is

designed for the TDA7492 high power dual BTL

class-D audio amplifier.

Due to the high efficiency, the TDA7492 device is

assembled in PSSO36 and is able to dissipate the

generated heating with the use of a reasonably

small heatsink.

On the board some jumpers allow to configure the

amplifier in order to verify all the features, such as

single ended or differential inputs, fixed gain

settings.

Standby and mute functions are enabled through

the microswitches provided.
