LINEAR INTEGRATED CIRCUIT
ataS10W CAR RADIO AUDIO
.D AMPLIFIER
ww DESCRIPTION
w The UTC2003 has improved performance with the same
pin configuration as the UTC2002.The additional features of
UTC2002,very low number of external components, ease of
assembly, space and cost saving, are maintained.
mThe device provides a high output current capacity(up to
3.5A) very low harmonic and crossover distortion.Completely
osafe operation is guaranteed due to protection against DC
and AC short circuit between all pins and ground, thermal
.cover-range, load dump voltage surge up to 40V and
fortuitous open ground.
