Description
The TDA7575B is a new MOSFET dual bridge
amplifier specially intended for car radio
applications. Thanks to the DMOS output stage
the TDA7575B has a very low distortion allowing
a clear powerful sound.
Among the features, its superior efficiency
performance coming from the internal exclusive
structure, makes it the most suitable device to
simplify the thermal management in high power
sets.The dissipated output power under average
listening condition is in fact reduced up to 50%
when compared to the level provided by
conventional class AB solutions.
This device is equipped with a full diagnostic array
that communicates the status of each speaker
through the I
possibility of driving loads down to 1Ω paralleling
the outputs into a single channel. It is also
possible to disable the I
TDA7575B by means of the usual standby and
mute pins.
