5 W + 5 W class-D audio amplifier demonstration board based on the TDA7491LP

The STEVAL-CCA029V1 demonstration board is designed for the evaluation of the TDA7491LP dual BTL class-D audio amplifier.

Due 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 the configuration of 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.
