July 2011 Doc ID 1459 Rev 21/2323 TDA2030A18 W hi-fi amplifier and 35 W driverFeatures Output power 18 W at VS = 16 V / 4 with distortion High output current Very low harmonic and crossover distortion Short-circuit protection Thermal shutdownDescriptionThe TDA2030A is a monolithic IC in a Pentawatt package intended for use as a low-frequency class-AB VS max = 44 V it is particularly suited for more reliable applications without regulated supply and for 35 W driver circuits using low-cost complementary TDA2030A provides high output current and has very low harmonic and crossover distortion. The device incorporates a short-circuit protection system comprising an arrangement for automatically limiting the dissipated power so as to keep the operating point of the output transistors within their safe operating range.
