YOUDA INTEGRATED CIRCUIT TDA2003
10W AUDIO AMPLIFIER—TDA2003
DESCRIPTION The TDA2003 has 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.
