Description

The STEVAL-CCA044V1 demonstration board is

designed for the TDA7498E 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 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.

Microswitches are also provided to enable the

standby and mute functions.
