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.
