■ Externally synchronizable
■ RoHS compliant
Description
The STEVAL-CCA043V1 demonstration board is
designed for the TDA7491MV mono BTL class-D
power 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 the configuration of
the amplifier in order to verify all the features as
single-ended or differential input, fixed gain
settings.
Microswiches are also provided to enable the
standby and mute functions.
