CV203 Datasheet PDF – Car Radio Audio Amplifer

Part Number : CV203 ( = TDA2003 )

Function : Car Radio Audio Amplifer

Package :  TO-220 5 Pin, Pentawatt 5 Pin Type

Manufactures : Huajing Microelectronics


CV203 datasheet


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 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.
