Description

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.
