STEVAL-CCA042V1: 20W x 2 @ 8Ω, 5 ~ 18V in, Class D

Summary

The STEVAL-CCA042V1 is a demonstration board designed for the evaluation of the TDA7491HV dual BTL class-D audio amplifier. This application note provides the board specifications and a quick-start list for standalone 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 a heatsink. Jumpers on the board allow the configuration of the amplifier in order to verify the input signal as single-ended or differential and choose the fixed gain settings. Microswitches are also provided to enable the standby and mute functions.
