TheTDA 2003 has improved performancewith thesame pin configuration as the TDA 2002.The additional features of TDA 2002, very lownumberof externalcomponents,ease of assembly,space and cost saving, are maintained.Thedeviceprovidesa high outputcurrentcapability(up to 3.5A) very low harmonic and cross-overdistortion.Completely safe operation is guaranteed due toprotectionagainstDCand ACshort circuit betweenall pins and ground,thermal over-range,load dumpvoltage surge up to 40V and fortuitous openground.
