STEVAL-CCA029V1: 5W x 2 @ 8Ω, 5 ~ 14V in, Class D

The STEVAL-CCA029V1 is a demonstration board designed for the TDA7491LP dual BTL class-D audio amplifier. This application note provides the board specifications and a quick-start list for stand-alone operation. Also included are the schematic, printed circuit board layout and bill of material.

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.
