  • 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 (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.
  • Hi-Fi Audio Power amplifier
