TDA2030AV STMicroelectronics

TDA2030A 18 W hi-fi amplifier and 35 W driver Features Output power 18 W at V = 16 V / 4 with S 0.5% distortion High output current Very low harmonic and crossover distortion Pentawatt (vertical) Short-circuit protection The TDA2030A provides high output current and Thermal shutdown has very low harmonic and crossover distortion. The device incorporates a short-circuit protection Description system comprising an arrangement for automatically limiting the dissipated power so as The TDA2030A is a monolithic IC in a Pentawatt to keep the operating point of the output package intended for use as a low-frequency transistors within their safe operating range. A class-AB amplifier. conventional thermal shutdown system is also With V = 44 V it is particularly suited for more included.
