TDA2030A
18 W hi-fi amplifier and 35 W driver
Features
■ Output power 18 W at VS = ±16 V / 4 Ω with 0.5% distortion
■ High output current
) ■ Very low harmonic and crossover distortion t(s ■ Short-circuit protection uc ■ Thermal shutdown rod Description te P The TDA2030A is a monolithic IC in a Pentawatt
package intended for use as a low-frequency
le class-AB amplifier. so With VS max = 44 V it is particularly suited for more b reliable applications without regulated supply and O for 35 W driver circuits using low-cost t(s) - complementary pairs.
Pentawatt (vertical)
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.
