The TDA2003A is capable of providing a highoutput current (up to 3.5 A) with very lowharmonic and crossover distortion.
Completely safe operation is guaranteed due toDC and AC short-circuit protection between allpins and ground, a thermal limiting circuit, loaddump voltage surge protection up to 40 V andprotection diodes in case of accidental openground
Improved performance over the TDA2002 (pin-to-pin compatible)
Very low number of external components
Ease of assembly
Cost and space savings
