DESCRIPTION
The TDA7575 is a new BCD technology DUAL
BRIDGE type of car radio amplifier in PowerSO36
package 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 superior efficiency perfor-
mance coming from the internal exclusive structure,
makes it the most suitable device to simplify the ther-
mal 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
2
C bus.
The TDA7575 has also the possi-
bility of driving loads down to 1
paralleling the outputs
into a single channel. It is also possible to disable the
I2C and control the TDA7575 by means of the usual ST-
BY and MUTE pins.
