UNISONIC TECHNOLOGIES CO., LTD TDA2030A LINEAR INTEGRATED CIRCUIT 18W HI-FI AUDIO AMPLIFIER AND 35W DRIVER „ DESCRIPTION The UTC TDA2030A is a monolithic IC intended for use as low frequency class AB amplifier. With Vs=max=44V it is particularly suited for more reliable applications without regulated supply and for 35W driver circuits using low-cost complementary pairs. The UTC TDA2030A provides high output current and has very low harmonic and cross-over distortion. Further the device incorporates a short circuit protection system comprising and arrangement for automatically limiting the dissipated power so as to keep the working point of the output transistors within their safe operating area. A conventional thermal shut-down system is also included. „ ORDERING INFORMATION Orderi [ ... ]
