Hello all! Nice forum!
I´m working on a robot lawnmover, have som problems with the buried wire fence. Found one simple circuit with a 555 as driver but I can´t understand how they use the TDA2003 as amplifier, actually I´m not sure that it is a TDA2003 used?? It just says 2003 (but 16 pin??)
Can anyone please understand this?
here is the pdf of the wirefence
