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 ...
