Product overview
Description
The TDA7575B is a new MOSFET dual bridge amplifier specially intended for car radio applications. Thanks to the DMOS output stage the TDA7575B 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 diagnostic array that communicates the status of each speaker through the I2C bus. The TDA7575B has also the possibility of driving loads down to 1Ω paralleling the outputs into a single channel. It is also possible to disable the I2C and control the TDA7575B by means of the usual standby and mute pins.
