Product Summary

The 7575BPD is a new MOSFET dual bridge amplifier specially intended for car radio applications. Thanks to the DMOS output stage the 7575BPD has a very low distortion allowing a clear powerful sound. The 7575BPD is equipped with a full diagnostic array that communicates the status of each speaker through the I2C bus. 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.
