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 I2C bus.
The I2C bus can be disabled and the device can
be controlled by standby/mute pin.
