Features: Input stage and gain compressor Over-modulation protection and current limiting Modulator DAC Step-up Mode control Diagnostics / safety Power control General Description: TDA7572 is a highly integrated, highly versatile,  semi-custom IC switch mode audio amplifier. It  integrates audio signal processing and power  amplification tailored for standalone remote bass  box applications, while providing versatility for full  bandwidth operation in either automotive or   consumer audio environments. It's configured as   one full bridge channel, using two clocked PWM   modulators driving external, complementary  FET's.  Broad operating voltage is supported, allowing  operation from both 14 V and 42 V automotive  power buses, as well as from split supplies for  consumer electronics use.  A current mode control boost converter controller  is provided to allow high power operation in a ...
