DESCRIPTION
The TDA7575 is a new BCD technology DUAL
BRIDGE type of car radio amplifier in PowerSO36
and Flexiwatt27 packages specially intended for car
radio applications. Thanks to the DMOS output stage
the TDA7575 has a very low distortion allowing a
clear powerful sound. Among the features, its superi-
or 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 lis-
tening 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
2
C bus.
The TDA7575 has also the possi-
bility of driving loads down to 1
Ω
paralleling the outputs
into a single channel. It is also possible to disable the
I
2
C and control the TDA7575 by means of the usual ST-
BY and MUTE pins.
