I found in my electronics box a TDA2004 and I didn’t knew what to do with it ( I just finished the exams and I needed a way to relax so … ) . After a short search I managed to find the application data for it (look at the bottom of the page for the download link).
According to it, TDA2004’s main features are :
- low distortion
- low noise
- high reliability ( protection against : output AC shortcircuit to ground, very inductive loads, overheating etc. )
- space and cost saving ( it needs only few external components : 12 capacitors and 7 resistors )
Below is the usage schematic, as you can see it is really simple ( 22 external components )
