TDA2006 12W AUDIO AMPLIFIER
May1995
PENTAWATT ORDERING NUMBERS:TDA2006V
TDA2006H
DESCRIPTION
The TDA2006is a monolithic integrated circuit in
Pentawatt package,intended for use as a low
frequency class”AB”amplifier.At±12V,d=10%
typicallyit provides12Woutput poweron a4Ωload
and8W on a8Ω.The TDA2006provides high
output current and has very low harmonic and
cross-over distortion.Further the device incorpo-
rates an original(and patented)short circuit protec-
tion 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 shutdown system is also included.The
TDA2006is pin to pin equivalent to the TDA2030.
