The TDA 2003 hasimproved performancewith the same pin configuration as the TDA 2002.
The additional features of TDA 2002, very low numberof externalcomponents,ease of assembly, space and cost saving, are maintained. Thedeviceprovidesa high outputcurrentcapability (up to 3.5A) very low harmonic and cross-over distortion. Completely safe operation is guaranteed due to protectionagainst DCand ACshort circuit between all pins and ground,thermal over-range,load dump voltage surge up to 40V and fortuitous open ground.
