This is an amplifier circuit with gain music output power up to 7W. It uses IC TDA2003 as main component. This 7 watt audio amplifier circuit is small but powerful multi purpose amplifier.
IC TDA2003 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.

How do i get working tda2003 in intercom system with speaker
Excellent website even for experts and new users
how many Volts do you need to get 7 W?
