Description
The TDA2030 is a monolithic integrated circuit in
the Pentawatt
®
package, intended for use as a
low frequency class-AB amplifier. Typically it
provides 14 W output power (d = 0.5%) at
14 V/4
Ω.
At ±14 V or 28 V, the guaranteed output
power is 12 W on a 4
Ω
load and 8 W on an 8
Ω
(DIN45500).
The TDA2030 provides high output current and
has very low harmonic and crossover distortion.
Furthermore, the device incorporates an original
(and patented) 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.
