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

MULTIPOWER BCD TECHNOLOGY

MOSFET OUTPUT POWER STAGE

PowerSO36 (Slug up)

ORDERING NUMBER: 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

through the I2C bus. The TDA7575PD has also the

possibility of driving loads down to 1Ω paralleling the

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

able the I2C and control the TDA7575PD by means of

the usual ST-BY and MUTE pins.
