Audio Power Amplifier with TDA2003
TDA2003 is a cheap amplifier that is designed to run on single rail power supplies (unipolar). It provides a high output current capability (up to 3.5A), very low harmonic and cross-over distortion.
TDA2003 has improved performance with the same pin configuration
as the TDA 2002. The 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 (max. 3.5A), very low harmonic and cross-over distortion. A 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.
ABSOLUTE MAXIMUM RATINGS:
VS - Peak supply voltage (50ms): 40 V
