TDA2003 10W HiFi Audio Amplifier IC

TDA2003 is a monolithic audio amplifier IC with a maximum output power of 10W. The IC provides a high current capability up to 3.5A and very low harmonic and cross-over distortion. The device is commonly used in stereo or mono audio circuits. 

TDA2003 features in AC and DC short circuit protection between all pins and ground, a thermal limiting circuit, load dump voltage surge up to 40V, and a fortuitous open ground, thus providing guaranteed completely safe protection.
