STEVAL-CCA027V1
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.
