Package
PowerSO36 package specially intended for car
radio applications.
Thanks to the DMOS output stage the TDA7564B
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 diagnostics array that
communicates the status of each speaker through
the I
