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 1O 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.Multipower bcd technologyMOSFET output power stageDMOS power outputNew high-efficiency (class AB)Single-channel 1 Odriving capabilityHigh output power capability 2x28 W/4O@ 14.4 V, 1 kHz, 10 % THDMax. output power 2x75 W/2O,1x150 W/1OSingle-channel 1Odriving capability84 W undistorted powerFull I²C bus driving with 4 address possibilities:StandbyPlay/muteGain 12/26 dBFull digital diagnostic (AC and DC loads)Possibility to disable the I²C busDifferential inputsFull fault protectionDC offset detectionTwo independent short circuit protectionsDiagnostic on clipping detector with selectable threshold (2 % / 10 %)Clipping detector as diagnostic pin when I²C bus is disabledStandby/mute pinsESD protection
