STEVAL-CCA028V1
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.
