■ Externally synchronizable
■ RoHS compliant
Description
The STEVAL-CCA042V1 demonstration board is
designed for the TDA7491HV 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 a heatsink.
Jumpers on the board allow configuration of the
amplifier 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
