DESCRIPTION

The TDA7575PD 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 TDA7575PD

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 simpli-

fy the thermal management in high power sets.The

dissipated output power under average listening con-

dition is in fact reduced up to 50% when compared to

the level provided by conventional class AB solu-

tions.

This device is equipped with a full diagnostic array

that communicates the status of each speaker

possibility of driving loads down to 1

Ω paralleling the

outputs into a single channel. It is also possible to dis-

the usual ST-BY and MUTE pins.
