Description

The TDA7567PD is a new BCD technology quad

bridge power amplifier in PowerSO36 package

specially intended for automotive applications.

Thanks to the DMOS output stage the

TDA7567PD 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

C bus.

The I

C bus can be disabled and the device can

be controlled by standby/mute pin.
