TDA2003 PDF – 10W Car Radio Audio Amplifier

Part number : TDA2003

Functions : 10W Car Radio Audio Amplifier.

Pacakge : Pentawatt 5 Pin

Manufacturer : STMicroelectronics,  Unisonic Technologies


TDA2003 Audio Amplifier


The Device is a monolithic audio power amplifier

integrated circuit. The TDA2003 has improved performance with the same pin configuration as the TDA2002. The additional features of TDA2002, 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.
