Description

The TDA2030A is a monolithic IC in a Pentawatt package intended for use as a low-frequency class-AB amplifier.

With 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 pairs.

The 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. A conventional thermal shutdown system is also included.
