TDA2003
10W CAR RADIO AUDIO AMPLIFIER
DESCRIPTION
TheTDA2003 hasimprovedperformancewith the
samepin configurationas the TDA2002.
The additional features of TDA 2002, very low
numberofexternalcomponents,easeof assembly,
spaceand cost saving,are maintained.
Thedeviceprovidesahighoutputcurrentcapability
(up to 3.5A) very low harmonic and cross-over
distortion.
Completely safe operation is guaranteed due to
ORDERING NUMBERS : TDA 2003H
protectionagainst DCandACshort circuitbetween
allpins andground,thermal over-range,loaddump
voltage surge up to 40V and fortuitous open
ground.
