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 PENTAWATT (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to ORDERING NUMBERS : TDA 2003H TDA 2003V 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.
