TDA7567PD:Intelligent high efficient (class SB) differential input, quad BTL output with full I2C diagnostics (turn on, permanent, ac)

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.
