TDA2030
14W Hi-Fi AUDIO AMPLIFIER
DESCRIPTION
The TDA2030 is a monolithic integrated circuit in
Pentawatt® package, intended for use as a low
frequency class AB amplifier. Typically it provides
14W output power (d = 0.5%) at 14V/4Ω; at ± 14V
or 28V, the guaranteed out put power is 12W on a
4Ω load and 8W on a 8Ω (DIN45500).
The TDA 2030 provides high output current and has
very low harmonic and cross-over distortion.
Further 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 working point
of the output transistors within their safe operating
area. A conventional thermal shut-down system is
