Please do not post the same question 3 times.

It is an audio amplifier IC. It has about 22 transistors inside.
Its output is only 1.5W at clipping into 8 ohms with a 12V supply or 2.8W at clipping into 4 ohms.
Its output is about 8W at clipping into 3.2 ohms with a 20V supply.

This IC is obsolete and has not been made for 12 years. The pins numbers on the schematic are completely wrong. The schematic is missing important parts. Make the circuit on the datasheet of the TDA2003 instead. It is available, shows all the parts and even shows a pcb design.
