Audio amplifier with IC AN7522, AN7523 and TDA2616

The series of amplifiers that are used on the television audio, amplifier used amplifier ICs, including the IC:

• AN7523
• AN7522
• TDA2616

Third series of the function with the same system, namely BTL (Bridge Transformer Less). By using such configuration we get several advantages, namely no use coupling capacitors or coupling transformers.
