rodDescription
te PThe TDA2030A is a monolithic IC in a Pentawatt
package intended for use as a low-frequency
leclass-AB amplifier.
soWith VS max = 44 V it is particularly suited for more
breliable applications without regulated supply and
Ofor 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.
