® TDA2003
10W CAR RADIO AUDIO AMPLIFIER
DESCRIPTION
The TDA 2003 has improved performance with the
same pin configuration as the TDA 2002.
The additional features of TDA 2002, very low
number of external components, ease of assembly,
space and cost saving, are maintained.
The device provides a high output current capability
(up to 3.5A) very low harmonic and cross-over
distortion.
Completely safe operation is guaranteed due to
protection against DC and AC short circuit between
all pins and ground, thermal over-range, load dump
voltage surge up to 40V and fortuitous open
ground.
