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 outputpower (d = 0.5%) at 14V/4Ω;at±14V
the guaranteedoutput poweris 12W on a 4Ω load
and 8Won a 8Ω (DIN45500).

TheTDA2030provideshighoutputcurrentand has
very lowharmonic and 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 outputtransistorswithintheir safe operating
area.A conventionalthermal shut-down system is
also included.
