SGS Thomson Microelectronics TDA2030 Datasheet
TDA2030
14W Hi-Fi AUDIO AMPLIFIER
DESCRIPTION
The TDA2030 is a monolithic integratedcircuit in
Pentawatt package, intended for use as a low
frequency class AB amplifier. Typically it provides
14W outputpower (d = 0.5%) at 14V/4Ω;at±14V
or 28V,the guaranteed output power is 12W on a
4Ω load and 8W ona 8Ω (DIN45500).
TheTDA2030provideshigh outputcurrentandhas
very lowharmonicand cross-overdistortion.
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 transistorswithintheir safeoperating
