STEVAL-CCA028V1: Stereo 10W @ 8Ω, 5 ~ 18V in

Summary

The STEVAL-CCA028V1 demonstration board is designed for the TDA7491P 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 any heatsink.

Jumpers on the board allow configuring 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.
